Coat Colour Combinations
With a few exceptions, all of the aforementioned dilutes and white patterns can exist in combination with each other; producing some unique, beautifully
coloured horses. Thus we get things like Classic Champagne Dun; Amber Cream Champagne; Grulla Roan; and many others. When you consider that AQHA registers
yearly 5% and less quarter horses as Blue Roan, Grulla, and other rare colours, it makes you realize that horses with combinations of colour genes are very special
indeed!
Coat Calculators
For those of you interested in seeing different coat colour combinations, this Link will take you to the popular Animal Genetics’ Coat Color Calculator:
https://animalgenetics.com/horse-coat-color-calculator/
If you want to include Seal Brown (At) and/or get a nice visual example of a horse’s colour, try this one (although it does not add up all the percentages like the
Animal Genetics calculator does): http://colorgenetics.info/equine/foal-coat-color-calculator
Another one that gives you a visual representation of different colour gene combinations is Jennifer Hoffman’s Visual Coat Calculator, here:
