You dont.... Make a new zip and add that to it, then open up notepad type:
Title: _____
Author:_____
Type a description here like: im cool and stuufz dis is mah colurz
So it should look like
Title:Mr.Snipe's colors.
Author: Mr.Snipe
This is my new color set
Then save it as description.txt and add it to that zip. i recomend you get RTB and then move that zip to your add ons. then start up blockland a press start game. Go to color manager then find Mr.Snipe's colors.
