How to write white letters on a black background. When to Use White Text on a Dark Background

The biggest fun (after shading, of course) is printing white letters on a black background. This is a very bold decision; besides, text printed in this way attracts the attention of others no less than a black eye. Therefore, use this technique carefully.

When you print white on black, remember that first you must create a black background, and then create white text. The black background is created as follows.

Select a text block.

It is best to start with a ready-made text. At some point you will end up with black text on a black background, so the text won't be visible. If you have a typed document, the completion of the procedure will be marked by its turning white. (For information about highlighting text, see Chapter 6.)

Select a team Format>Borders and Shading.

A dialog box will appear Borders and shading.

Make sure the tab Fill is in the foreground.

If not, click on the tab's shortcut. Tab Fill will appear in the foreground (see Fig. 19.5).

In the area Fill select black color.

This is the fourth square from the top in the first column; you will see a message in the field to the right of the color picker Black.

Click the button OK to leave the dialog box Borders and Shading.

Now you can't see anything because you're looking at black text on a black background. (Actually, if the text is selected, you'll see a stunning sight: a large white block floating in a sea of black. Don't be scared!)

With the block still selected, change the text color to white. To do this, use the button Font color on the formatting toolbar.

A drop-down palette will appear.

Select an element in the palette White.

(This is the last square of the palette, located at the bottom right. If you move the mouse pointer over it, a tooltip with the word White will pop up.) Click on this square to change the font color.

Now you should deselect it. The text will become visible on the screen: white letters on a black background.

Word displays inverse text quite effectively on the screen, especially when it is selected. I bet you anything - you will never be able to “lose” such text even in a very large document!
I don't recommend inverting large chunks of text. On many printer models, such text is printed “it doesn’t matter.” This technique works best for highlighting headings and small pieces of text.
If you have problems printing inverse text, change your printer settings. In the dialog box Seal click on the button Options. In the area Printer click on the button Properties. As a result, a dialog box will appear on the screen Printer properties. Click on the tab icon Graphics. In the area Graphics mode check the box Dot graphics. Click the button OK to close the dialog box Printer properties.

What I don’t like about Chrome is the flickering of the white background when drawing a page. As far as I understand, this happens at the engine level, and cannot be changed at the user level, even if you change the colors in the OS. I think that at this point we need to throw a stone at the Chrome developers. Why do they determine the color of the canvas themselves, and not take it from the OS system settings? The same goes for Skype and a number of other “serious” applications.

Opera

Not so much with Opera. All I could find was the Contrast Changer extension. Or a simpler option in the form of bookmarklet.
As an alternative to Clearly, you can use the online service Instapaper and their bookmarklet.
Also, the Stylish extension has recently appeared.
Selecting a dark theme. For example, Opera Simple Dark.

To change the interface color:
File > Options > General > User Interface options > Color Scheme: Black. To change the color of the paper (background), you need to change the colors in the OS.
I can't help you with older versions of Office.

Another bonus of “white on black” for mobile devices is that this combination consumes less energy(because it emits less light). How much less? Don't know. I suspect that with prolonged reading it is quite noticeable. It would be interesting to see the statistics.

Vision hygiene

Contrast

As mentioned above, don't use too much contrast (max white on max black). Contrast ≠ readability. Light gray on dark gray is perceived more comfortably. Which shade of gray exactly is selected individually.

Contrast plays a role not only in the image on the display, but also with the world around you. That is, take into account the lighting in the room and try to avoid too much contrast between the lighting and the brightness of the display/colors. This is especially true for night owls. If you already work in the dark, switch to dark color schemes - your eyes will be much less tired. The contrast between a dark and light theme in a dark room can differ by 20 times or more!

Distance

Don't forget about the inverse square law. If you are used to leaning towards the monitor, then when reading, increase the font size ( Ctrl+) and lean at least 15cm more back. This will significantly reduce the amount of light emitted to the eyes. Of course, the monitor has too large an area to consider it a point light source and apply this law to it. But as a simple example shows, when the ambient light is not too bright, leaning back from a distance of 55cm to 75cm, the illumination from the monitor decreases by 1.5 times (and even more in the dark). The recommended distance from the monitor is 50-70cm.

Breaks

Regular breaks from working at the monitor are more beneficial for vision than all of the above combined. But how does one remember to take regular breaks?

I absolutely love the Workrave app. Adjustable for different time intervals and pauses of different lengths (for example, 3 short ones every 15 minutes, 1 long one every hour). It can block the system for a certain time without the possibility of canceling, which is very motivating to get up from your desk :) It has many little conveniences in the settings. For example, a few seconds before blocking, a warning pops up, and if you are too busy and don’t have time to pause, then you just continue working - the application will notice the activity (keyboard, mouse) and cancel the blocking. It also independently determines when you take a break and resets your timer.

Exercises

I suspect that most readers are familiar with the symptoms of computer vision syndrome such as spasm of accommodation (pseudomyopia, false myopia) or dry eye. There is enough information on the Internet on how to prevent these disorders through various exercises and gymnastics for the eyes. The main thing is to do them regularly, at least several times a day. I would like to separately note 2 types.

Human vision is designed in such a way that the normal state of the eyes (when the eye muscles are relaxed) is accommodation into the distance. Because the monitor is normally located relatively close to the eyes, the ciliary muscle is constantly tense to keep the lens convex for close focusing. This leads to fatigue and spasms of the ciliary muscle (pseudomyopia), and over time to permanent visual impairment. Alternately looking far and near, compensates for this stress, for which you definitely need to break away from the monitor (which Workrave helps well) and periodically exercise at the window for a few minutes.

The second type is face palming.

face palming

Yes, yes, that's it. So every time you react to an epic fail, you have the opportunity to stretch your eyes. This method is also known as palming. There is still a lot of speculation and controversial personalities surrounding this word. Therefore, I will immediately make a reservation that I recommend this exercise Not as a method to improve vision, and as a method to relax the eyes. Darkness gives the photoreceptors the opportunity to “rest”, and the warmth of warm hands dilates the blood vessels of the eyes and stimulates blood circulation. It will also moisten the eyes, since for some reason a person blinks much less when working at a monitor. Well, considering that the brain spends most of its energy on processing visual information, this is also a way to relax the gyrus a little.
(house) and without lighting (at night). Daylight was excluded because the result strongly depends on many factors (for example, weather) and has a large scatter in measurements.
Distance. For the long distance I took the length of my arm to be 75 cm. For the short distance - a slope of ~20 cm forward closer to the monitor.
Display brightness. In conditions without lightening, I carried out measurements twice - with the maximum display brightness and, accordingly, the minimum.
Measurement results. I compiled all the data into one table. For comparison, I used the ratio between illumination in different conditions. As can be seen from the table, with “average” lighting, leaning back, the illumination decreases by 1.5 times. And in the dark, if you use a dark scheme, then the illumination decreases by 25 times.
Disclaimer! The results of the experiment do not claim to be universal, since the experiment was done “on the knee”. But I dare to assume that similar results will be observed in many everyday situations.

Bright colors attract buyers

How to attract customers with color?

Color range, in which the store is located, provides strong impact on the visitor in the process of choosing a product and making a purchase. Each color sends a conditioned signal to the client’s subconscious and awakens a certain emotion in response. We invite you to familiarize yourself with the basic laws of color psychology.

Statistics show that perception deteriorates in the following order:

black letters on a yellow background
black letters on a white background
yellow letters on a black background
white letters on a black background
blue letters on a white background
white letters on a blue background
blue letters on a yellow background
yellow letters on a blue background
green letters on white background
white letters on a green background
brown letters on a white background
white letters on a brown background
brown letters on a yellow background
yellow letters on a brown background
red letters on a white background
white letters on a red background
red letters on a yellow background
yellow letters on a red background

But the impact of advertising media is just the opposite, which is why red usually used to highlight price tags with discounts and promotions. Most often, a red background and yellow or white text are used for this.

And for store decoration they use less provocative combinations.

Under the influence warm colors(shades of red, yellow and orange) buyers usually feel a surge of energy, these shades stimulate the psyche. Therefore, experts recommend using them to “warm up” store visitors.

Cold spectrum colors (shades of blue, cyan and violet), on the contrary, reduces nervous system activity. Under their influence, store customers feel more relaxed and calm.

Warm colors: buy without hesitation!

The strongest in the warm range is, of course, red . Red is able to activate all functions of the body: under its influence, breathing accelerates, muscles tense, and the heartbeat quickens. Properly placed accents on red in the interior of the store may increase number of impulse purchases.

Discount promotions

However, with red you should be more careful and use it precisely as accents, and not as the main background. Overdoing it with red can make shoppers overly impatient, anxious, and cause them to quickly leave without making a purchase.

The surge of energy causes orange, but its excess in space is annoying, therefore, like red, it is harmonious only in the form of an accent color.

Pastel shades of orange evoke associations with beauty and golden tan. They are often used in the design of sales areas with goods for women.

Yellow stronger than others attracts attention, so perfect suitable for decoration various promotions and special offers.

Marketers noted that in combination with red yellow is associated from buyers with affordable prices. Therefore, this color scheme is very often used in discount stores.

Cool colors: enjoy a calm choice

Cool colors and their shades do a great job creating in the store relaxing and calm atmosphere.
Buyers influenced by blue, cyan, violet spend more time studying shop windows and choice, worry less about possible expenses. The cool range of colors is the most appropriate in expensive stores or those in which there are often queues.

Blue associated with constancy and usually causes feeling of well-being. It helps to better assimilate information and promotes trusting communication, therefore it is most suitable for decorating luxury goods stores, the purchase of which occurs after weighing all the pros and cons.
