I'm not too fond of that for the same reason. I'm wondering: We already can set different face attributes depending on DISPLAY's 'background' property, which can be 'light' or 'dark'. Say the user is working with a 'dark' background by default, but we now detect that one of the font-lock faces has not enough contrast when highlighted by the region: why not simply switch to the face that is defined for 'light' background instead? -David
