The theme comes in three variants, "Soft Light", "Medium Light" and "Hard Light". Soft and Medium are even yellower. This is so often the case with Gruvbox themes. I just want a white background, is that so unusual? 🫠
(Yes, that's a screenshot of my terminal with the theme applied. Yes, I am one of those monsters that use a terminal with light theme.)
I try to kick my circadian rhythm with ample light, so for that I switch between light and dark theme more or less around sunrise/sunset. Staring into a bright screen with light theme isn't as bright as being outside, but then I can at least also turn on all kinds of lights or sit outside somewhere, without it being as detrimental to readability as it would be with a dark theme.
