I don't think there is a built-in gradient function, but you could do
something like this:

>>> import Image
>>> import ImageDraw
>>> im = Image.new("RGB", (100, 100))
>>> draw = ImageDraw.Draw(im)
>>> for l in xrange(100):
...     colour = (0, 0, 255 * l / 100)
...     draw.line((0, l, 100, l), fill=colour)
...
>>> im.show()

You have to adjust for the size and colours you want of course, and change
the loop so that the gradient is in the right direction.
