Title: Shift HSV-color
Post by: Hedgeberry on July 12, 2022, 12:55:55 pm

Is there any built-in HSV-color shift functionality?
Let's say I need to shift the color shade by 32, is there any simple way to do it or will I have to write my own RGB to HSV conversions, shift and convert back there?

SFML doesn't offer any color space conversion, everything is in RGBA.

So yes, you'd have to convert it. Entering "HSV SFML" in a web search, I ended up with: https://gist.github.com/marukrap/7c361f2c367eaf40537a8715e3fd952a
