Thank you for this new informations which will be useful to me in the future. To answer your question, I use the following color profile sRGB IEC61966-2.1, but I also did tests with CMYK giving the same results.

Great! It works like a charm! Thank you so much for your help

The black color is not display in black but in dark blue in Affinity Designer interface. If I export my test file with a simple black rectangle in a other format as PNG or SVG the color is well display in black in the exported file. I tryed all available configurations (RVB/8-sRGB, CMJN-...) but nothing changed. Thank you for your suggestion. I am working with Affinity Designer, released 1.7.3.481 on Windows.
