Re: Paint Formulas

Color matching is as much art as science. paint formulations can vary slightly and be visibly different; your paint can weather or age, changing color. Doing it by the numbers will not give an exact match, unless you are very lucky or have failing eyesight.

Lets say that I could print an exact match visually for my blue...if you then measured the two, chances are the paint would not match perfectly. Why? Because the chemistry of the colors is different.

Same problem trying to read a paint chip. Colors that appear to match are formed of different amounts of different colors. They might match in sunshine and be different under streetlights, or cloudy skies.

I used to do work for Sears (when they were on Homan) who discovered that bathroom items (towels, shower curtains, mats, soap dishes, toilet seats) would match in the store but mismatch under incandescent or fluorescent light. Housewife would return them and be mightily irritated. They spent a lot of ytime and money working with vendors to fix things.

99 times out of 100 it just isn't simple or easy!
