Swapping between editors, it seemed like nova was slightly different / washed out to my eyes. I didn’t really think much of it until I tried to modify my own theme. I’m not sure if this is a bug, or if there is a specific reason for this, but it does appear that colors are not what is defined in the theme.
If I’m not mistaken, this has more to do with differing “Color Profiles”… I also use Xscope, but I’ve seen this many times with other color pickers as well, where the picked color does not match the one specified (e.g. when picking a color from a webpage where you know the exact hex/rgb value).
i think vscode must be forcing a color profile. i started changing colors in multiple apps and selecting different color profiles. vscode changed until i relaunched, and then it went back to displaying “correctly”.
