It is a smart thing to check your design for color contrast. Typography must be legible. Check My Colours is here to do the job. Unfortunately, it doesn’t “see” background images. Still, it’s a free diagnostic tool that’s worth a quick look.
[CheckMyColours.com] is a tool for checking foreground and background color combinations of all DOM elements and determining if they provide sufficient contrast when viewed by someone having color deficits.
A typographic, designological, visulicious extravaganza!
