In an ocean of charcoal, slate, and black bikes, I just appreciate the wide range of colors Rivendell puts on their bikes.
However, I have what I think is a minority opinion: I’m about 75 percent in favor of no more than two specific colors for specific models (**with exceptions for custom paint jobs, which are at the buyer’s discretion, with Riv’s final approval of course**). The production colors become part of a particular model's “brand" or visual identity. This is important.
For example, it’s hard to imagine Atlantis production models in any color other than the Atlantis blue/green… even though there are Atlantises painted in lovely one-off colors. It would be odd if any other production model were painted in the Atlantis color. The Atlantis geometry has changed tremendously over the years. You might even say that the Atlantis green/blue *is itself* a huge part of the Atlantis brand because the color has been a constant through the various Atlantis permutations.
Another example: I like that Hunqs came in two color schemes: the early runs were grey and kidney bean red, and the later runs were green. Now Joe’s fantastic custom was inspired by the grey and red Hunq scheme. But it’s a custom, a one-off, slightly different, and ultimately it was Joe’s prerogative. He made a very tasteful choice.
I think the Platypus was the first model in mermaid (?). Anyway, when I see mermaid I think Platypus, not Gus or anything else. I don’t get why any model other than the Platypus should be in mermaid! It’s a strong brand association. The lovely sparkly raspberry of Leah’s Platypus, being a unique one off, does not weaken the Platypus mermaid brand because raspberry was not a production color.
And as much as I like the lovely olive green as a color, the number of models in this green suggests brand confusion and inconsistency.
I do think that variations of similar colors across model is fine. They should be different enough not to confuse them, though.
Like I said, my opinion is probably in the small minority.
