>Celeste, the unique color of Bianchi, has continued to evolve from the first inspiration of the pale sky blue of the Campionissimo Coppi era, to the recent adaptations of turquoise and fluor greensit's changed over the years from a sky blue to a mint green, with all manner of variations. oftentimes it will change from model to model. like, my 2020 "celeste" aria is a dark turquoise, while a "celeste" volpe from the same year is a light mint green. I've heard stories about how, decades ago, the color would drift from batch to batch of paint and you'd get variations within a single model. not sure how true that is, but it wouldn't shock me. this goes into it a little more:
