color values change itself on Lab sliders

[user1984]

I have a little problem with colors in Lab.

If I try to create a swatch for a RAL standard color eg. RAL 5005 (see https://en.wikipedia.org/wiki/List_of_RAL_colors ).

The Lab values are L=32 a=-7 b=-37 type that in and close the box.

When you reopen it the values are changed to L=32 a=-5 b=-35

The bug is not present if you change the color of the fill direct - not the swatch - then you can reopen the dialog and there are the same values.

Initial color change:

 

Reopen the color dialog:

Everything is correct!

 

This is a bug in the complete Affinity Range. Testet on Designer, Photo and Publisher in the latest versions 1.7.1

It happents at most with colors outside the sRGB gammut I think. And independet what color space the document is, Lab/16, sRGB/16, sRGB/8, ProPhoto/16 ... at least if you have no document open at all.

Is there a solution for the problem ... do I something wrong?

By the way, is it possible to lock swatches from change the color of it?

I checked the latest version an in Beta Version 1.7.2.2 RC1 the bug is still present.

Hi user1984,

Thanks for letting us know. I've reproduced this and will get it passed on to development.

I think this is the same issue as the other colour sliders are exhibiting...
