My love of MATH

This post is a dedication to my obsession with COLOR and math.  The calculations below are used to determine what would best be described as a color's "DNA".  All three of the equations are methods of creating a color space and are used by the printing and design industries to maintain color accuracy. I became interested in color theory during my time at The Art Institute of Colorado.  Creating my first ICC profile was a revelation that turned into a passion.  As an artist, having the ability to print what you have created, exactly how you have envisioned it is a must! And this is how we achieve those results . . .

The color difference, or ΔE, between two colors L1a1b1 and L2a2b2 is:Equation 1

Delta E (CIE 1994)

The color difference, or ΔE, between a sample color L2a2b2 and a reference color L1a1b1 is:
Equation 1

Equation 2

Delta E (CIE 2000)

The color difference, or ΔE, between a sample color L2a2b2 and a reference color L1a1b1 is:
Equation 1

Peacock TREND

Summer 2010 : Tara

Couldn't help but make my own "peacock" palette

I have had a few requests for the breakdowns for this color palette
so I'm including the RGB breakdowns as part of the post.

Since RGB is a larger gamut you will notice a brighter appearance;
if you would like CMKY (as seen in the original posting) create document
in RGB and switch document modes in CMYK.

Enjoy!
