Lab color value with decimals place

[smg]

How is possible to read a lab color with at least 2 decimals place?

Some time I need to be more precise, may be a great idea to implements this feature in all the suite

It isn't values are shown rounded. - The same seems to apply (or applied, don't know if it has been changed in the meantime over 4 years now) to PS according to this older PS 2019 version reading ...

• Adobe Color Picker 2019: Decimal places possible in InDesign and Illustrator

Though via PS scripting one can get pretty much more as an output read than only two decimal places ...

• Inaccurate values when converting from RGB to L*ab colours (see the accepted PS script rgbToLab example answer there)

Maybe, time will tell.

You can add a feature request, as far as there isn't already one for this ...

• Feedback for the Affinity V2 Suite of Products

... though I doubt that it will speed up things time wise here, as there are more urgent things to fix and do.

Displaying decimals in colour value fields is not just adding a feature to the interface but appears to affect the way how Affinity handles / calculates colours generally. It is a known issue, discussed and logged/tagged a few times since V1 that different interface items may report differing values for identical object colours, here is a recent discussion for instance:

As Affinity uses the LittleCMS color engine as it's underlaying CMS here, you can read more about ICC profile conversion handlings, the general ICC Floating Point Encoding Range, floating point precision & representation, clipping color values to be inside realizable gamuts etc. here ...

• Unbound Color Engines
• Gamut visualization
• PhotoLine - Really lossless convert from RGB to LAB possible only in 32 bit depth (uses LittleCMS too)
• ... and so on ...
