216 colour cube
Saturday, February 19th, 2005“The Netscape palette for foreground colors usually (but NOT always) consists of all the combinations of 00, 33, 66, 99, CC, FF for each of the red, green, and blue elements of the color descriptor. This results in 216 (6×6×6) distinct colors.” – Victor Engel
