Confused ? Basically, its like if you show a human a 1024 color screen and then show him a 24-bit (16 million) color screen; he will not be able to tell the difference. BUT, if you put the two screens side by side, he can tell the difference ! > This means that when you get to 24 bits of color information, there > is no point in going any further. > I pretty much believe that 256 colors is just about enough. Of course the more the merrier, may be 1024 ?? But I really believe that we need at least 16 bit (or 65536 colors) colors to really do nice display. Why ? Well, these days, we really want multiple Windows on screen each having their own 1024 palette or so. So, I think PC's 256 color standard is deficient. Mac's 24 bit colors is overkill but I don't mind if the display card is not too bloody expensive. Regards, ## Life is fast enough as it is ........ Peter Lim. ## ....
