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.

For those interested in this topic, I found minutephysics' treatment of this subject to be really pleasant and easy to grok. I had a talk I gave at work once or twice discussing color conversion and I would play a 90 second snippet from this …

In What every coder should know about Gamma CorrectionGood 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 …

In What every coder should know about gammaIf we're on the "watch this YouTube video if you work with colours" train, here's a great explanation of why gradients usually have a dark band in the middle, on the MinutePhysics channel: [VIDEO] In short: the RBG values in an image are not actually …
