As you have probably noticed the return value of askcolor() is something
like:

>>> askcolor()
((214, 215, 214), '#d6d7d6')

where the second part is the original color string as returned by
tk_chooseColor , the first part, the 3-tuple, was apparently brought to us
by Frederik Lundh, who wrote the tkColorChooser module. The magic lines
from tkColorChooser.py are:

        # to simplify application code, the color chooser returns
        # an RGB tuple together with the Tk color string
        r, g, b = widget.winfo_rgb(result)
        return (r/256, g/256, b/256), str(result)

so you see, the triple is simply a tuple of (red, green, blue) color
values, ranging from 0 - 255 .

I hope this helps

Michael
