为什么值得看
文章揭示了sRGB/Display-P3色域无法覆盖的宽谱青色，解释了显示器"缺青色"的物理根源。对做计算机视觉、图像算法或显示技术的工程师有参考价值，涉及色彩空间转换和HDR内容制作时需注意色域映射陷阱。
编辑判断
做AI图像生成或视频生成的团队容易忽视这个坑：Stable Diffusion和多数扩散模型在sRGB空间训练，生成的"青色"其实是压缩后的近似值。如果你在做品牌色还原、电商视觉或印刷对接，模型输出直接喂给广色域屏幕会出偏色。
一个具体行动：检查你的图像管线是否做了正确的ICC色彩管理，而不是假设"RGB就是RGB"。这在医疗影像、卫星遥感等需要物理准确性的场景里代价更高。

核心争论：屏幕色域局限催生对新型显示技术的期待，metamerism现象引发对色彩本质的深层讨论
What an truly incredible article, particularly the way the color space diagrams are used to gradually tell the story (and the prose is great too). I actually want to read it again tomorrow morning in more depth.
Really nice article, I'll look closer to green lights next time I see one. The most striking experience I had was working with a blue laser (430nm). The best way I found to describe its color is that it was screaming "blue" at me. Since then, I'm always disappointed when looking at a screen displayi
Sounds like we need the next VR glasses to shine colorful lasers into our eyes instead of screens.
