As I understand it, standard RGB monitor gamma (as defined by the hardware) gives a non-linear brightness response to voltage. Hence mid grey value 127,127,127 would appear on the monitor noticeably lighter than 'mid grey'. Mac gamma attempts to compensate for this so that increases in numeric tonal value produces a linear increase in screen brightness. So IMO it's a case of the Mac got it right in this case, but unfortunately 'most computer users' don't seem bothered if 'dark blue' (#000033) looks indistinguishable from black (#000000), near enough seems to be good enough, ho hum. martin baxter _______________________________________________ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
