Colour Picker App#
While there are a load of rgbahsv colour pickers out there it is still useful to make one.
Let's use the colour picker in paint.net as a pattern, keeping it simple at the start, use the canvas to display our gradient, then use a scale underneath the canvas and a spinbox to show the value of the scale. If both the scale and its associated spinbox point to the same tk variable they should affect each other. At the same time the gradient should change with the value shown on each colour component.
In case you are wondering, the following scripts are DPI aware, so they have an enlargement factor included, and will operate at 96dpi and 192dpi equally well, for larger dpi remember to run the colour wheel script 09colour_wheel_pil.py and adjust.
