I know, I know. Bianchi Celeste is a range of colors. There is no match. I know that. But I'm planning to have a Bianchi powder coated and I want to pick a color I'll be happy with. Picking a color that I will look at and think, "Yes, that's Celeste" is pretty easy. There are a lot of choices. What I'm shooting for is picking one that I won't look at and think, "That's not exactly the shade I'm looking for."
Challenges:
1. There are many shades of Celeste that vary from year to year and bike to bike, even in the original
2. Pictures of colors on computer monitors introduces at least three more degrees of variability
3. Powder coating seems to allow some variation of color based on base material and depth of powder, maybe other factors
I'm just putting that out there so no one else has to say it. I know. I acknowledge. I accept the risks.
Now then, I've narrow it down to three candidates from Prismatic Powders and ordered swatches. Here's a picture, with a Hudz "Eroica Celeste" brake hood and a tube a Phil Waterproof Grease for reference.
On my monitor, that's a reasonably close approximation of what my eye is telling me. From left to right, that's "Sea Foam Green", "Pearled Turqoise", and "Tropical Breeze".
But wait, there's more! Here are some references cherry-picked from the Internet, because these uniformly don't look like the swatches.
Sea Foam Green
Pearled Turqoise

(The above are the same wheels.)
Tropical Breeze
Helpfully, Tropical Breeze (top) and Sea Foam Green together
I think what I want to end up with is this:
Or maybe this:
What do you think? Any suggestions?
