- 5.14.1 context attributes <https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.14.1> discusses drawingBufferColorSpace and unpackColorSpace - 5.14.8 texture objects <https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.14.8> discusses unpackColorSpace This spec was originally developed in the W3C's ColorWeb community group <https://www.w3.org/community/colorweb/> along with the 2D canvas color management proposal at https://github.com/WICG/canvas-color-space/blob/main/CanvasColorSpaceProposal.md It was broken out and iterated upon separately in Khronos (in particular by Mozilla and Chrome representatives). The final changes to the Khronos WebGL spec are in https://github.com/KhronosGroup/WebGL/pull/3292 *Summary* Implementation of WebGL color management API WebGL allows specification of - the color space that its drawing buffer is - the color space that content should be converted to when importing as a texture This feature is to update our implementation to include this functionality. Prior to this feature, both of these defaulted to sRGB. Now they can also use "display-p3".

Canvas 2D color managment API already TAG reviewed at https://github.com/w3ctag/design-reviews/issues/646 This specification change was developed in Khronos and followed the processes there. Risks Interoperability and Compatibility Gecko: Positive Developed in close collaboration with Mozilla, spec changes reviewed by Mozilla. WebKit: Positive Discussed in ColorWeb CG with WebKit representatives Web developers: Strongly positive Other signals: Privacy: N/A This exposes no information about the user's system to the web. This API can be used on systems that do not support wide color gamut (the out-of-gamut colors are clipped, as they are for 2D canvas, images, and video). Security: N/A This allows a WebGL canvas to specify its color space. This functionality is already present for 2D canvas, images, and video content. Debuggability Debugging is currently limited to sRGB colors. This limits visibility into wide color gamut image, video, and 2D canvas. This limitation is being looked at in the context of adding CSS color level 4 support. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?No, this is tested instead by WebGL conformance tests.
