	Different color depths have different color codes, this is why rgb() is useful: it returns the appropriate code, based on the current color depth.

Different color depths have different color codes, this is why rgb() is useful: it returns the appropriate code, based on the current color depth. When in 8bit mode, this code is 0..255 and when in 16bit mode 0..65535.

		+	Using this function in different color depths can be tricky. This is because rgb() will return a different color code under different color depths.
		+	For example, when at 8bit, we do:
		+	<pre>my_color = rgb(100,100,100);</pre>
		+	my_color will most likely have the value ''6'' at this time. Suppose we change the color depth to 16bit now, using [[set_mode]](). Now, my_color holds a totally different color than before, as ''6'' is nowhere near rgb(100,100,100) in 16bit mode. To counter this effect, my_color needs to be reinitialized:
		+	<pre>my_color = rgb(100,100,100);</pre>
		+	The same code, but rgb() now returns the proper code, as it always returns the code belonging to the current color depth.
		+	my_color will now be about ''25388''.
