Vocaloids used to be able to fit into colour schemes, but since we have so many now this has broken down. We have simily run out of clearly definable colours. If you observe all the official Vocaloid's boxart, you will see that it is common for several to share the same dominant colour.

There's still a million shades out there, of course. But yes, a mascot having a dominant colour in their design isn't really that big of a thing.
