In the 216 "web safe" colors, each R, G, or B value is either 00, 33, 66, 99, CC, or FF. This was back when many computers could only display 256 colors at a time and Windows and MacOS each had 40 different colors reserved. If you picked a "random" RGB value, the OS\browser on a 256 color display would have to pick some color to replace it.
