Comment (by lobais):

 I've made this python algorithm for generating colors.

 If you want 10 colors, you call it with genColor(1), genColor(2),
 genColor(3)...
 Then it will genereate 10 colors which looks good, and lies as far from
 each other on the colors circle as possible.

 It will always start at the same place on the colorcircle, so if you don't
 want all chats to start with a person in red, you can generate a random
 seed 0-1 and give to all genColor calls in that chat.

 def genColor (n, startpoint=0):
     assert n >= 1
     # This splits the 0 - 1 segment in the pizza way
     h = (2*n-1)/(2**ceil(log(n)/log(2)))-1
     h = (h + startpoint) % 1
     # We set saturation based on the amount of green, in the range 0.6 to
 0.8
     rgb = colorsys.hsv_to_rgb(h, 1, 1)
     rgb = colorsys.hsv_to_rgb(h, 1, (1-rgb[1])*0.2+0.6)
     return rgb
