I also prefer light colour schemes. Didn't use to, I used dark themes (like gruvbox) for a while, until I learned the value of not having my monitors blast my eyes with 100% brightness. Solarised actually helped me go from dark to light themes as the yellowish background and lower contrast were easier on my eyes than white and high contrast.

Even since I learned to turn down my monitor brightness so that white on my monitor is about the same brightness as a white piece of paper in the room, I have been very fond of Prot's Modus Operandi (https://protesilaos.com/emacs/modus-themes).
