//| .. 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::
//|
//| palette[0] = 0xFFFFFF # set using an integer
//| palette[1] = b'\xff\xff\x00' # set using 3 bytes
//| palette[2] = b'\xff\xff\x00\x00' # set using 4 bytes
//| palette[3] = bytearray(b'\x00\x00\xFF') # set using a bytearay of 3 or 4 bytes
