计算机里的颜色是坏的

MinutePhysics explains that computers store brightness nonlinearly, so blurring and blending colors in raw RGB gives wrong, dark results. It shows why mixed colors, such as in gradients, look off.

Why HN likes it: HN cites it as the accessible go-to explanation of gamma and color blending errors in image programs.

“I found minutephysics' treatment of this subject to be really pleasant and easy to grok.”
