Here is an Rainbow Writing worksheet that I used with kindergarten and 1st grade. I have my students copy down the challenge/high frequency words of the week using crayons and various colors. The students enjoy this activity because they can choose various colors to write with.
I have the file in both Rich Text Format for Windows/Mac (so you can edit) and PDF. There are also fonts included.
