Use math to generate ideal colors in Contrast Checker #127
Description
Is your feature request related to a problem? Please describe.
When I'm using the "Contrast Checker" functionality, my goal is to not only check the contrast, but adjust the color to meet a set standard. This is rather difficult to do with this tool because you don't have fine control over even HSL values.
Describe the solution you'd like
Below each standard rating, it should show you the minimal color difference required to meet the standard, with a toggle between to choose if this value is generated using the text or background color.
Describe alternatives you've considered
Giving access to HSL sliders would at least allow me to manually tweak settings, but as it is (and this may be a Gnome thing), I can only modify HEX values, which isn't the easiest thing to do by hand when trying to keep a consistent color. With HSL I can typically just tweak the lightness value until I meet the desired value.
Additional context
While this site doesn't show you ideal values automatically, it does allow changing between rgb and hsl values, making it much easier to dial in to meet a desired standard.
