zviI converted rb's Easyread style to a layout layer. (You can see it live at http://zvi.dreamwidth.org/?s2id=86436 You can apply it to your own journal via Advanced Customization. The layout layer is #73107. The green theme is #73183.)
I'm trying to figure out what colors to use to make 3-4 high contrast color themes. My specific questions are
Foreground/background : what are the minimum brightness and color difference levels to use for low vision users? I've seen brightness 125, color difference 500. I've also seen (I think in an alternative measurement to color difference) that the contrast ratio should be either 4.5:1 or 7:1.
Adjacent text (i.e. plain text next to links) : what color difference minimum? Is there a brightness minimum? Is there a contrast ratio minimum?
I am planning to check my color contrasts with this Colour Contrast Check tool. If you know of a better one, let me know.
Also, I know there's red/green colorblindness and blue/green colorblindness ... any other color combos to avoid?
