Description

Hi. Quite excited about the work you're doing.

Reading over the white paper, I noticed that the acceptable range for color values is set to be [0,1]. Does this imply that nonconforming color spaces should be excluded?

For example, ACES 2065-1, CIE LAB/LUV and OKLAB can have negative color values. Now, perceptual color spaces might be a questionable choice here, but it seems conceivable that someone would want to define their materials with AP0 primaries.

Research direction

Start by reading the white paper and the 51-comment discussion, then compare the stated [0,1] constraint with the cited ACES 2065-1, CIE LAB/LUV, and OKLAB cases. Done means the project records a decided policy on whether such color spaces are supported or excluded and updates the relevant specification text.
