为什么值得看
Multi-Primary Color Display 用超过传统的 RGB 三原色（如 RGBCY 五色）来扩展可显示色域，解决现有屏幕无法还原真实世界色彩的问题。对做视觉 AI 训练数据、AIGC 内容生成、XR 设备的团队有直接影响，色域标准可能面临换代。
编辑判断
现有 AI 视觉模型的训练数据几乎全基于 sRGB/Rec.709 色域，这意味着模型对真实世界高饱和色彩的'理解'本身就是残缺的。如果多原色显示成为主流，从数据标注标准到生成模型的输出空间都需要重构。
做 AIGC 视频生成、3D 渲染的团队现在就应该关注 OpenColorIO 和 ACES 的色彩管理管线是否支持多原色工作流，避免两年后被动适配。HDR 内容的合规检测工具也可能出现新机会。

Can anyone explain how this works? Humans have 3 (sometimes 4) cones, so I thought that going beyond 3 primaries wouldn't increase the perceivable gamut. Update: thanks for all the great explanations!
I don't know either, but if we visualize the RGB color space as a triangle that is entirely contained within the weird shape that represents the set of all colors the human eye can perceive ( https://en.wikipedia.org/wiki/RGB_color_model#/media/File:CI... ), presumably
Cyan is severely under-represented by monitors, so the extra pixel is a dedicated cyan. It dramatically improves the ability to display blue/green colours. *edit: found the link I was after on this: https://moultano.wordpress.com/2026/06/19/where-to-find-the-...
