I have a question about colouring. Ripley is a very dark blue roan - the roaning being restricted to chest, tummy, toes and muzzle. She is beginning to get tan colouring appearing over her eye brows, cheeks and muzzle - this has started only 3 months ago or so. The colouring is turning her previously black areas to a chocolatey / tan colour. Two of her litter had 'and tan' colouring - dam is a red, sire a blue roan. Will the full tan marking develop and has anyone come across this before. I am quite excited she looks even more lovely !!
