Rendering intent not being respected switching color spaces inside Swatch-Panel
so apparently the rendering intent set in the document OR the application isn't being respected when the color space of a swatch is being changed e.g. from RGB to CMYK.
Tested in InDesign 15.1.3 and 16.0.1
Steps to reproduce:
1 create a new document, with working spaces sRGB and "PSO coated v3" (profile available on eci.org)
2 create a swatch, e.g. RGB 0 / 98 / 227
3 change to CMYK, results in the correct 90,64 / 63,6 / 0 / 0
- go back to step 2
- change the "Solid Color" rendering intent of the document to Perceptual
- now change the RGB swatch to CMYK again, results in the same, but now definitely WRONG color value.
after changing the rendering intent the swatch should result into
89 / 64 / 0 / 0
Be aware: this only affects switching the swatch. If I keep the RGB swatch and export to PDF with color conversion the applied color is correctly converted.
It doesn't matter which color space is used , RGB -> LAB also results in the exact same values.*
[edit: * this sentence is nonsense since rendering intent is used for mapping LAB to CMYK/RGB]
Thanks in advance

just wanted to add,
the difference seems to little to care, but try it with
RGB 0 / 27 / 227
then it becomes
100 / 86 / 0 /0 (relative, which apparently is always used)
98 / 78 / 1 / 2 (percetual, according to Photoshop)
