See attached example inside CoronaColor.
If the sRGB is checked, CoronaColor reports the value as linear (during RC candidates, it was linear check-box).
Secondly, in either case, the "Value" is always in sRGB. Is this by design ? It's bad name in such case. And exact linear value has to by typed into R/G/B values instead.
Funny enough, it matches if I check "values are in linear space" check-box in CoronaColor.
So what's happening ? Is new picker wrong ? is CoronaColor wrong ? It's behaving very confusingly.

Hi Juraj.
May you take a look at

Hi,
I looked at the problem and it is caused by unchecked "input values are in linear color space" (which is checked by default). This checkbox is pre-coronaImrpovedPicker and does the same thing as sRGB checkbox in the color picker (but inverted). Since both do the same thing, they clash together when both are used. You should reset it to defaults to get expected results.
We talked about the situation and we will try to solve the confusion about sRGB/linear spaces by:
- A writeup "what is this and why should we care?" - done: https://forum.corona-renderer.com/index.php/topic,13833
- adding a tooltip to sRGB checkbox in color picker
- replacing "input values are in linear color space" with either sRGB checkbox to be consistent with color picker, or replacing both with linear vs. sRGB radio with proper tooltips
- Disabling "input values are in linear color space" or equivalent control in CoronaColor map when "Solid color:" is used and Corona Improved picker is used, since it is redundant in that case.
