THE VIDEO SHELF · gamma and color blending

Computer Color is Broken

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.

  • Good reminder about these persisting blending issues in the linear interpretation of RGB values, which was well explained to non-coders as well here in a quite popular MinutePhysics video: [VIDEO] As others commented the gamma scaling issues seem even more relevant. Just please, don't use …
