A method for selecting a 24-bit RGB color using chance operations.

A method for selecting one of 16,777,216 RGB colors using chance operations.

1. Toss three coins.
2. Cast line:

  • 2 heads + 1 tail, or 3 tails = solid line [–––]
  • 2 tails + 1 head, or 3 heads = broken line [–  –]

3. Repeat coin toss six times, building a hexagram from the bottom up.
4. Use light grey chart to look up hexagram and corresponding number.
5. Find this number on the dark grey RGB chart and note the corresponding four number sequence (for example, if the “32″ hexagram is generated, the four number sequence would be 124, 125, 126, 127).
6. Repeat steps 1 through 4 to generate another hexagram number.
7. Find hexagram number on the RGB chart and note the corresponding selection number 1–4 at the bottom of the column (for example, if the “45″ hexagram is generated, the corresponding selection number is 3).
8. The selection number identifies which number in the four number sequence to select.
(In the example above, 3 is used to select the third number: 126.) This is the red (R) value.
9. Repeat steps 1 through 8 two more times for the green (G) and blue (B) values.

Example:
