1496In addition to the colours defined above, @@RXVT_NAME@@ offers an 1499The following text gives values for the standard 88 colour mode (and
1497additional 72 colours. The first 64 of those (with indices 16 to 79) 1500values for the 256 colour mode in parentheses).
1498consist of a 4*4*4 RGB colour cube (i.e. I<index = r * 16 + g * 4 + b +
149916>), followed by 8 additional shades of gray (with indices 80 to 87).
1500 1501
1502The RGB cube uses indices 16..79 (16..231) using the following formulas:
1503
1504 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1505 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1507The grayscale ramp uses indices 80..87 (232..239), from 10% to 90% in 10%
1508steps (1/26 to 25/26 in 1/26 steps) - black and white are already part of
