<originalMessage> <snip> Is that an exhaustive list of colors? 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white What about 38 and 39? I could just try it, but knowing my luck, it would just lock up the whole terminal forever. </snip> </originalMessage>
FWIW, color space is 3-dimensional and with VDT's, the dimensions are red, green, and blue. The ANSI color controls allow each dimension to be set full on or full off (binary) with no in-betweens giving 2^3 = 8 possible colors. For ANSI, these are numbered 0 to 7, adding 30 for foreground colors or 40 for background colors. The numbers are not arbitrary: 0 = 0 + 0 + 0 (black) 1 = 0 + 0 + 1 (red) 2 = 0 + 1 + 0 (green) 3 = 0 + 1 + 1 (red+green=yellow) 4 = 1 + 0 + 0 (blue) 5 = 1 + 0 + 1 (red+blue=magenta) 6 = 1 + 1 + 0 (green+blue=cyan) 7 = 1 + 1 + 1 (red+green+blue=white) --Ken Nellis -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
