Coloration is a deviation from a desired response. "
This is a very simplistic view because coloration can be caused by many things other than just a simple deviation from FR. For example we have THD which can be perceived in a music reproduction system as coloration but it is something other than just a FR deviation or anomaly. In an analog-based system we can have minor speed errors that may not detectable as such but which are interpreted by the ear/brain interface as "coloration" in the music reproduction system. So to Mr. Burwen's claim that we just need an equalizer to insure proper performance - that's simplistic to the point of being just wrong.
