def ColorSpread(count, saturation, lightness):
'''
Compute a stepped spectrum sequence of color values that are evenly
distributed around the 360 degree hue wheel. Returns an array of rgb
values in hex.
Arguments:
count The desired number of colors
saturation Color saturation level, from 0 to 1
lightness Color lightness, from 0 to 1
IMPORTANT: all values must be expressed as floats, even if they are
round numbers
EXAMPLES:
>>> a = ColorSpread(6.0, .7, .8)
>>> a
['F07575', 'F0F075', '75F075', '75F0F0', '7575F0', 'F075F0']
>>> for x in a:
... print "#%s" % (x)
...
#F07575
#F0F075
#75F075
#75F0F0
#7575F0
#F075F0
