[yolotad]

You want to learn how to index an image? Here's how!

What you'll need:
-Irfanview
-Paint XP
type it up on Google.

Step 1: Background

Spoiler:

Open your image in paint XP and make the background of your image a color thats not in it. I choose green as its not in my sprite.

Save it and name it something like [Yourname]unindexed.

Step 2: Irfanview

Spoiler:

Open your unindexed image up in Irfanview and hit Image>Decrease Color Depth. Choose 16 colors and uncheck Floyd Steinberg Dithering.

Then hit Image>Palette>Edit palette
Swap your background color and the first color around. it should look messed-up

Then hit save. Name it something like [Yourname]Almost indexed

Step 3: Getting the colors right

Spoiler:

Open up the messed-up image in Paint XP and goto Edit>Paste from

Select the unindexed image.

SAVE! you're done. right click on your image and click properties>information and bit-depth must be at 4 or else you have done something wrong!
