YB Pieds, aka "Pumpkin Pieds", are very cool! Like most they loose some color with age, the oranges fading to more of a burnt yellowish. I think they look great as babies and adults! Billy has an 843 gram 2017 YB Pied (het lavender but that wont affect it visually) up for sale that is a good example of how they age:
