Traits

Dilution is a recessive gene that lightens a cat's coat overall. Dilution (dd) turns Black cats Gray (Sometimes called “Blue” in real life, such as the Russian Blue breed), Red cats Cream, Yellow cats Sand, Blue cats Ice. 

These are basic color palletes for each of the dilute coat colors. You are not required to color pick these when designing your cat as these are only guidelines!
