@darius @mcc Do you have a favorite article on the subject? I think I usually end up sharing https://www.antipope.org/charlie/blog-static/2010/12/invaders-from-mars.html but I'm wondering if anyone has posted anything more in depth.

Sometimes I want to make a browser-based art tool, but then I remember that browsers don't have any built-in gamma correct alpha blending. I could implement my own, but I'd have to implement everything else too, like masking and vector graphics paths. Which is exactly the sort of reinventing-the-wheel that I enjoy doing, but I don't have enough free time to justify adding all that to my side projects so instead I just get sad.

Wait what if I just convert all my colors to linear RGB values anyway, use those in standard browser graphics APIs and pretend that I'm doing all blending in linear RGB space, then perform a single transformation on the final image to convert it to real sRGB for display? I'd probably lose a lot of color depth in the darker colors unfortunately, maybe too much to be worthwhile. :/
