What triggers some colors to switch to CMYK?

When I work on color gradients I mostly use HEX codes to add the colors in RGB.

Somewhere along the process I discover (through exported fonts which don’t look as intended) that many colors have switched to a CMYK profile.

I am curious if there is any action that triggers this, which I can pay my attention to going forward?

Is there a quick way to convert all CMYK colors in the palette to RGB profile?

Thanks! :slight_smile:

I have never seen that. Can you send me the file?
