The CIE has published the CIECAM02 Color Appearance Model, which includes a calculations to estimate brightness, "Q".

Yes, but I do not see it useful. Things (like the simplest one, monitor characterization and profiling) are not improved.

I offered the information to Jackdan because it will help answer his questions. It might be useful to him.

So is a warning that it may be not useful.

It does require some study to make it useful, however. I know that some profiling software only allows lightness ("J") and not brightness("Q") in their calculations so limit what you can get out of CIECAM02 to little more than what CIELAB provides.

I used my own implementation, worked 3 years on it.
