Should Lab and HCL colorspaces clamp luminance to [0, 100]? #2

They currently do, but I don’t think it makes sense. It only makes sense for RGB because of machine limitations. I suppose we could force the luminance to be non-negative, but I don’t think there’s any reason to limit the maximum value to 100.
