That's because you're not looking past the obvious. You think that 12 bits means 4 bits each of Red, Green, and Blue. Wrong, Godzilla Breath! :-) :-) 12 bits means you got 4096 colors. If you've got a palette of 16 million colors then you've got a lot of freedom. The hard part is to pick out the *right* 4096 colors. It has something to do with your eyeball's non-linear response to light of varying wavelengths. For example, your eyes aren't all that sensitive to large changes in yellow density at high luminance, so you only need a few shades of yellow to keep you covered. Likewise with various shades of blue. What you need is a monitor that has sufficient flicker-free resolution that at normal viewing distance the dots are smaller than the point spread of the optics in your eyeballs. With that requirement satisfied, you can create the illusion of a continuous tone image with only 4096 colors. The current amiga display is not good enough to do that trick. >... >and the conclusion is we'd like 'colors that are closer together'; there >is just too much of a difference between (0, 0, 7) and (0, 0, 8). Ok, so just *make* them be closer together. I don't mind. Really. >I've seen the Eikonix stuff at shows, it's real nice. So how do you do >it, eh, Kevin :-) Wouldn't you like to know? :-) Hey, if you've seen our stuff, then you should be satisfied with the challenge that you set forth above. The display you saw was only 4096 colors. I'm just not allowed to say *which* 4096 colors we use, or how we determined them. That's for us to know and the competition to figure out.
