1. Introduction

2. Color-matching Function RGB

This is a catalog of accurate graphics for color science.The EPS files can be downloaded as TXT files. Then rename as EPSand use in any desktop publishing program like PageMaker or InDesign.Previews can be shown by Photoshop but these are already rasteredwhereas the EPS files contain scaleable vector graphics.Don´t use parts of this document by copy and paste. This doesn´tdeliver the best quality.The use of the graphics files is free but the author should be mentioned.Many other graphics and tutorials available. Please refer to the Websiteand the chapter Documents.
