Chapter 6. Deeper into Graphics > The power of palettes

The power of palettes

We experimented with color palettes back in Chapter 3, demonstrating how they can remap the monitor's display to match their collection of colors. But how are they really useful?

Look at it this way: Color is a resource. Like any resource, color needs to be managed to be put to best use. Although you could conceivably save every graphic Cast member as a 32-bit element (with a palette containing all possible colors), it's unlikely that you'd want to—you'd be wasting RAM and clogging up processor time, invariably slowing down your movie. With color palettes, you can have only those colors you need read into RAM, which enables optimum playback without compromising visual quality.
