how can I generate a Blue fonts

[yangbisheng2009]

        background = (0, 0, 255)  # random_color(238, 255)
        color = (0, 0, 255, 255) # random_color(0, 200, random.randint(220, 255))
        im = self.create_captcha_image(chars, color, background)
        #self.create_noise_dots(im, color)
        #self.create_noise_curve(im, color)
        im = im.filter(ImageFilter.SMOOTH)

When I set the 'color' Blue to 255(Red=0, Green=0), it seems that no use. The font is not blue.
Would you like help me. Thank your very much

See my gist. You only need to remember that RGB of your favourite blue colour and put it in the code.
