Looks nice, thanks.
I just chose a slightly darker module header color as I found it too bright and not enough contrasty compared to the active button.
It was inspired by the Arc colour scheme from KDE, which is indeed a bit cold. I always use the “toggle color assessment conditions” to check the colours and saturation of my photos as a white border gives you a bit of context, but I understand the theme can alter how we perceive the colours.
Thanks, will give it a try. I’ve been using Andy’s theme for a month and it’s an improvement for me. I haven’t noticed any problems with lateral adaptation effects while using the white border.
