I have a little problem. I have a foreground and background colour specified as RGB values (0-255) and need to know if they will be visible against each other. If not, then I need a replacement colour that will be visible against the background and a replacement background colour that will be visible against the foreground. By visible, I mean that text should be easily readable. I can work it out for elementary cases, but have no idea of say RGB(128, 93, 187) against RGB(187, 64, 192). Could any kind souls who have solved this please send me either the method or the code (C preferred). I prefer email to followups. Thanx Roger roger binns rdb@oasis.icl.co.uk ICL, bracknell, uk
