Color Entry

The tkColorChooser module can be used to specify an RGB color value.

tkColorChooser.askcolor([color [,options]]). The convenience function returns two values; the first is the color as a RGB triplet (a 3-tuple containing the red, green and blue values as integers in the range 0-255), the second a Tk color string. To preset a color when you display the dialog, you can pass a color (in either format) to the function.

If the dialog is cancelled, the function returns (None, None)
