中文导读
MinutePhysics 深入浅出的色彩科普：计算机是以非线性（Gamma 空间）存储色彩亮度的，如果直接在未经校正的原始 RGB 空间做模糊或色彩混合，会导致画面发暗失真，这正是许多图形渐变看起来极其脏浊的根源。
为什么 HN 推它
HN 讨论数字图像色彩混合、Gamma 校正原理以及各类图形软件踩坑时的必读标准科普指南。
「MinutePhysics 对这个话题的剖析真的既舒服又好懂。」HN 网友原话：I found minutephysics' treatment of this subject to be really pleasant and easy to grok.
英文原摘要（HackerTube / Claude 整理）
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.
HN cites it as the accessible go-to explanation of gamma and color blending errors in image programs.
HN 上的提及
Even Apple don't care to make their blur effects correct - see
I'd already seen most of this in a video
which was well explained to non-coders as well here in a quite popular MinutePhysics video
(Computer Color is Broken, MinutePhysics)
Non-linear color space causes errors in manipulation.
