The third rule of being a top designer: contrast, contrast, contrast
In design, good contrast is closely related to color selection. Contrast means that in your design, the difference in the degree of color between colors. Lightness is how bright or dark the color looks. Once saw a blank canvas for the title of the joke, someone said: "Look, this is a white cow in the snowstorm!" "This is an example of no comparison. White on top of white is no contrast, you can not see anything.
Is it childish? I mean, does this guide look stupid? Do I need to explain something? Is this concept very slow?
Instead.
Because unfortunately, I've always seen designers have a lot of problems with comparisons. Not only that, but when the comparison is appropriate, it can be a very important design technique.
I have often seen this mistake: designers use different colors to produce contrasts rather than different lightness. For example, a medium-value blue is placed on the red top of a median to produce a contrast. You can see the difference between the two. However, when you put two different colors together with one color, it creates a "sense of vibration" (because of the subtle contrast, it also creates a very significant, vivid and powerful color effect). You will notice that when the blue and red meet, your eyeballs will vibrate back and forth between the two colors. Can almost feel the pulse of the text.
If your goal is to make something energetic, you can use this technique. But it's hard for the eyes, and most people find it annoying. Here's another example that uses a different color but has a stronger contrast:
The second one is obviously easier to accept for the eyes.
