Color does so much for a design piece, yet it is so subjective. The light on the color, the substrate under the color and the eyes that see the color are all variables in viewing color. A graphic designer needs to address these variables as well as those that exist in reproducing color:
- Photographic / Additive Color (RGB) Red, Green and Blue phosphers are what make up the colors on your tv screen and computer monitor. Red, Green and Blue dyes are used in photographic paper to yield fulll color photographs. Red, Green and Blue yield a beautiful range of color, but is expensive to print in large quantities.
- 4 Color Process / Subtractive Color (CMYK) Cyan, Magenta, Yellow and Black are the 4 colored inks used to reproduce color photographs and images on press. They are also used in your color printer. It is a cost effective way to print full color, but does not reproduce as much of the spectrum as Red, Green and Blue.
- Web Safe Color originally there were only 216 colors that could be successfully displayed over the web. HOWEVER as technology moves forward more and more browsers can display additional colors. The cast of those colors is determined by the monitor and system they appear on.
- Pantone Matching System - Color matching system for inks devised by Pantone, Inc. to maintain color consistency in printed reproduction. Pantone colors can be used as a less expensive alternative to 4 color process. Pantone colored inks can also be used as a 5th and 6th color to maintain control and gain more latitude in process printing.
