There is an idiom in China called "Black and white", the white Paper has written a dark word, read it is no longer clear. Described the clear text credentials, do not allow repudiation or repentance. Until now, the white paper is still our most commonly used type, writing tools and colors are more and more diverse, but our most commonly used writing color is inseparable from black, blue, red and other colors. Try to write with a highlighter? Isn't that a trouble for yourself?

In fact, whether the color can be clearly identified depends on the difference in lightness:

  1. The color of the rendering effect and the background has a direct relationship:

The color itself has different lightness, in different background will have different effects, in the diagram below this picture we can clearly see different colors in different lightness of the background, will show different effects.

  2. Color brightness difference affects the readability of the font

We convert the above color to gray level can clearly understand the difference in the brightness of different colors, and according to its lightness intensity to rearrange it as follows:

As shown on the left side of the picture, the yellow color is very close to white, so using a yellow font on a white background makes the font difficult to read. The same reason, although Green and orange, red and purple hue is not the same, but because their brightness is very close, so in this collocation will make the text very difficult to read.

And on the right side of us in the same background, choose its completely different lightness color of the text color, reading has improved a lot.

Now you know why color blindness analysis always looks so hard:
