Submitting colours as tuples results in no colour plots in server session.

[copperwire]

When pushing a set of tabs with line elements to a bokeh server you get grayscale lines if colours were specified in touples.

Rough example:

from bokeh.plotting import figure, curdoc
from bokeh.models.widgets import Panel, Tabs 
from bokeh.client import push_session

import numpy as np

tabs = []

x = np.linspace(-2*np.pi, 2*np.pi, 200)

colour_list = [(51, 153, 51) ,(153, 51, 51), (51, 51, 153), (153, 51,153 ), (153, 51, 51)]

y = np.sin(x)
w = np.cos(x)

z = np.arcsin(x)
u = np.arccos(x)

v = np.arctan(x)
r = np.tan(x)

list_of_axis = [(y,w), (z, u), (v,r)]


for two in list_of_axis: 

    figure_obj = figure(plot_width = 1000, plot_height = 800)   
    figure_obj.line(x, two[0], line_width = 2, line_color = colour_list[3])
    figure_obj.line(x, two[1], line_width = 2, line_color = colour_list[1])

    tabs.append(Panel(child = figure_obj, title = "two by two"))

tabs = Tabs(tabs = tabs)
session = push_session(curdoc(), url = "http://localhost:1027")
session.show()
