I simply pick colors one after the other, and do not change already picked colors. As far as I can tell the golden ratio is the optimal way for this use case.

Using this you can still use saturated colors.

I have done something very similar in a ColorUtils for Java. I find it's an interesting but very subjective matter and for many practical uses, you will want to seed the algorithm with avoidable colors. I attacked the problem looking at the color space as a HSV cone, placing points as far away from another in a 3D space (and often seeding the algorithm with the color black and white).
