From the official UT2K3 website:
It appears that some of the manuals are printed in Orange Font. Please note that this was a mistake at the printing press, and we are offering a .pdf version of the manual. You will need to have a free version of ADOBE ACROBAT installed
Even though an orange font colored printed manual could be considered a 1337 collector's item, I'm sure the "affected" people will appreciate this. Additionally, having the pdf manual can fill some emptyness if you're not one of the lucky ones to own UT2003 (yet).
