Simple color setting to plots

Hi,
I’m trying to set colors of a line graph, however I keep getting error which I’m not able to resolve.

I’ve a function which takes in a string and a pandas dataframe:

def plot_metric(app_field, data):

colormap = {'android ': 'red', 'iphone': 'green', 'web_denzel': 'blue', 'all': 'red'}

colors = [colormap[x] for x in data['app']]

p.line('start', 'scaled_impact', source=data[data.app==app_field], color = colors)

I keep getting error:

ValueError: expected an element of either Enum('aliceblue', 'antiquewhite', 'aqua', 'aquamarine', 'azure', 'beige', 'bisque', 'black', 'blanchedalmond', 'blue', 'blueviolet', 'brown', 'burlywood', 'cadetblue', 'chartreuse', 'chocolate', 'coral', 'cornflowerblue', 'cornsilk', 'crimson', 'cyan', 'darkblue', 'darkcyan', 'darkgoldenrod', 'darkgray', 'darkgreen', 'darkgrey', 'darkkhaki', 'darkmagenta', 'darkolivegreen', 'darkorange', 'darkorchid', 'darkred', 'darksalmon', 'darkseagreen', 'darkslateblue', 'darkslategray', 'darkslategrey', 'darkturquoise', 'darkviolet', 'deeppink', 'deepskyblue', 'dimgray', 'dimgrey', 'dodgerblue', 'firebrick', 'floralwhite', 'forestgreen', 'fuchsia', 'gainsboro', 'ghostwhite', 'gold', 'goldenrod', 'gray', 'green', 'greenyellow', 'grey', 'honeydew', 'hotpink', 'indianred', 'indigo', 'ivory', 'khaki', 'lavender', 'lavenderblush', 'lawngreen', 'lemonchiffon', 'lightblue', 'lightcoral', 'lightcyan', 'lightgoldenrodyellow', 'lightgray', 'lightgreen', 'lightgrey', 'lightpink', 'lightsalmon', 'lightseagreen', 'lightskyblue', 'lightslategray', 'lightslategrey', 'lightsteelblue', 'lightyellow', 'lime', 'limegreen', 'linen', 'magenta', 'maroon', 'mediumaquamarine', 'mediumblue', 'mediumorchid', 'mediumpurple', 'mediumseagreen', 'mediumslateblue', 'mediumspringgreen', 'mediumturquoise', 'mediumvioletred', 'midnightblue', 'mintcream', 'mistyrose', 'moccasin', 'navajowhite', 'navy', 'oldlace', 'olive', 'olivedrab', 'orange', 'orangered', 'orchid', 'palegoldenrod', 'palegreen', 'paleturquoise', 'palevioletred', 'papayawhip', 'peachpuff', 'peru', 'pink', 'plum', 'powderblue', 'purple', 'red', 'rosybrown', 'royalblue', 'saddlebrown', 'salmon', 'sandybrown', 'seagreen', 'seashell', 'sienna', 'silver', 'skyblue', 'slateblue', 'slategray', 'slategrey', 'snow', 'springgreen', 'steelblue', 'tan', 'teal', 'thistle', 'tomato', 'turquoise', 'violet', 'wheat', 'white', 'whitesmoke', 'yellow', 'yellowgreen'), Regex('^#[0-9a-fA-F]{6}$'), Tuple(Byte(Int, 0, 255), Byte(Int, 0, 255), Byte(Int, 0, 255)), Tuple(Byte(Int, 0, 255), Byte(Int, 0, 255), Byte(Int, 0, 255), Percent) or RGB, got ['blue', 'red', 'green', 'blue', 'red', 'green', 'green', 'red', 'red', 'red', 'green', 'red', 'red', 'red', 'red', 'green', 'red', 'blue', 'red']

Following the same example as in the gallery: http://bokeh.pydata.org/en/latest/docs/gallery/iris.html

Any help will be appreciated.

Thanks.

Nevermind. Please ignore. Resolved!
