Color spaces nightmares : gamut clipping, WTF ?

But the black luminance is also defined by the medium (remanent brightness of the LED panel or ink density for paper), and that luminance is never zero. So RGB values should not be below that black threshold either, which is handled by black point compensation in some properly managed apps, but is less known and randomly implemented.

@anon41087856

Ensure your apps are properly color-managed, meaning they do gamut mapping (perceptual or relative colorimetry) and black point compensation when converting to other spaces (BTW, darktable doesn’t black point).

Given the first quote, what is the reasoning for darktable not applying black point compensation?

Also, while the gamut compression in Color Calibration is brilliant for smooth gradients in the master/working profile, are there any plans to add gamut compression for the output profile?

Amazing work, once again.
