The color is effectively an extra sticker and some software. All that's different between the screens is a color filter is added as layer during manufacture. With the software changes it knows which pixels to make white or black when combined with the filter to make the desired color. There are a bunch of tradeoffs with this method. Contrast is worse because of the color layer, color has lower DPI too.
