+//|   .. method:: __setitem__(index, value)

+//|     Sets the pixel color at the given index. The index should be an integer in the range 0 to color_count-1.
+//|
+//|     The value argument represents a color, and can be from 0x000000 to 0xFFFFFF (to represent an RGB value). 
+//|     Value can be an int, bytes (3 bytes (RGB) or 4 bytes (RGB + pad byte)), or bytearray.
+//|
+//|     This allows you to::
