bokeh: List of color tuples broken?

I think that bokeh doesn’t properly support lists of colors at the moment.

from bokeh.plotting import figure, show, output_file

output_file("broken.html")
xs = [1,2,3]
ys = [1,2,3]
col = [(255, 0, 0), (0, 255, 0), (0, 0, 255)]

p = figure(title = "Broken")
p.circle(xs, ys, radius=.25, color=col)
show(p)

When I run this code, I get 3 circles with no color. The documentation seems to suggest that colors can be passed in this way.

bokeh.version is 0.9.2

This issue is mentioned in the docs:

but that’s confusing, because the issue was closed in February yet the docs are describing problems that are presumably unresolved. Also, the docs in this screenshot say that RGBA hex colors are allowed, i.e. hex strings with 8 color characters, yet there seems to be an explicit limitation to 6 color characters in hex strings, based on this message when setting a color property:

(I.e., there is a regexp specifically looking for a {6}-hex-character string, but nothing allowing an 8-hex-character string.)

FYI I made a note in the new issue to make sure hsl(.....) etc is correctly handled.
