Hi Ben,
About "16 Bit Graphic Editors" of January 27:
MS> It seems not all 256 colours are safe.
AJ> Nope. Netscape's coders decided that there would be a palette that
AJ> would be safe on all platforms (back when displays were limited to
AJ> 256 colours) -- the 16 system colours (red, green, blue, yellow,
AJ> cyan, magenta, black, white and the lighter shades of each), plus
AJ> 216 others. 216 is the largest value of n^3 under 256; n here is 6.
Well, i read that `Windows' reserved some twenty colours of its own
and that combined to the `NetScape' story explains why i didn't get more
than six solid shades of grey in `PaintBrush', i guess. It makes sense!
AJ> The numbers are 0, 33, 66, 99, CC and FF...
Thanks a lot for these clear explanations. Euh... But i would bet
i have seen more than six solid shades of grey in `GrafX v2.00', or it's
probably just a combination of greys with very slightly tainted greys...
AJ> So as long as each component has one of those values, you'll see the
AJ> same colour (in theory) in any browser.
Ha. Now i really begin to see the light! There are a couple other
properties of the pixel, as i recall. Would that be an other way to mix
the numbers than using RGB hex values or will it allow more grey shades?
I'll keep your numbers at close reach from now on. Thanks Ben! :)
