Here's a simple alternative: pick a number of colors N such that they're
not readily distinguishable (let's say 13), and pick N colors evenly
distributed around the color wheel. Then pick a number Q relatively
prime to N (say 5) and somewhere between N/3 and 2N/3 as the basic step
between colors. Give the first branch you encounter color 0, the next Q,
the next 2Q, until it wraps around:

>>> [(x * 5) % 13 for x in range(13)]
[0, 5, 10, 2, 7, 12, 4, 9, 1, 6, 11, 3, 8]
