In the table above, you should especially focus on the data that I marked in red. Amazing, right?

Information should never be presented solely with the help of colors. Do you still not see the one marked in red? This is because the table illustrates how frustrating it can be not to be able to distinguish certain colors. Many people have a hard time distinguishing between red and green, so if you use colors to emphasize something, choose a colors such as blue.

In the example above, it would be possible to indicate something with an asterisk in addition to a red marking, which you then return to in your text.

Contrast

When choosing colors for your page, keep in mind users who are visually impaired and have difficulty distinguishing contrasts. This also applies to, for example, graphics or lecture presentations.
