About pallets and pallets pointers

Submitted by Weird Person on May 21 2005.
Here are my notes about how palletes work on Sega Genesis, and where are the palletes in Sonic 2.

First, what is a pallete? A Pallete in Mega Drive means various words, and each word means a color. But what color each word means? It's easy understand it, look the Following word (The Number is in Binary...)

0000 BBB0 GGG0 RRR0

The "B" means the Blue intense.
The "G" means the Green intense.
The "R" means the Red intense.

What that means? For Example, If you want the lighter Red , you will have to have no Blue intense, and no Green Intense, But you will need the Red intense. so , the word (that will means the Red color.) will have to be the Following:

000E

With this word, you get the lighter Red.
If the color value is High, So The color will be Lighter. If the color value is low, The color will be darker.

And remember, you can use more than Blue, Green and Red. For Example, if you want a purple color, you will need mix blue with red. Look:

0E0E

The Color above is the Lighter Purple.

Understand it? If Yes, go ahead and see the Offsets of each pallete, and for what each pallete is used for.
