The 216 browser-safe colors

These colors, defined numerically, should look the same on any browser. Each six-digit hexadecimal number is actually three two-digit numbers all rammed together. The first tells how much red to use, the second how much green, and the third how much blue, with 00 being none and FF being maximum. For color consistency, the numbers should be one of the following: 00, 33, 66, 99, CC, FF. Other numbers are permitted, but may look a little bit different on different browsers.
