Whatever allele that copy is specifies their feather color.

//Alter nothing below! As I was going through some old Racing Pigeon Pictorial magazines, dated August 1984, I came across an article on "Can Colour Be a Guide?" (One sentence should suffice.) The domestic pigeon (Columba livia) has three common iris colors, orange, pearl (white), and bull (dark brown), segregating in a single species, thereby providing a unique opportunity to identify the genetic basis of iris coloration.

Here, we identified the genetic basis of pearl (white) iris color in domestic pigeons (Columba livia) to explore the largely unknown genetic mechanism underlying the evolution of avian iris coloration.

If it were simply a matter of melanosomes lacking TYRP1, we would expect 'ash-red' to behave just like the 'brown' allelebut it doesnt. that dulls the color, and the tail is more brown than red. Thats because theres enough normal TYRP1 being made from the 'blue' allele for the birds to be able to make black melanin. It is not uncommon for the inexperienced fancier to confuse
