I say this every time, but listen to Ludwig
That’s a beautiful looking bike. The single colour frame absolutely pops, and the reason for that is that it is not competing with a horrific Hodge-podge of (rarely fully) matching components elsewhere that only serve to dilute the striking aesthetic contrast.
Go to an art gallery. Do they show the works off on your Nan’s Laura Ashley wallpaper? No, it’s almost always mounted on plain backgrounds. It makes the focus the focus and makes it stand out.
Many people would argue that you should break convention and go nuts, making your bike look like a bag of regurgitated Haribo, but those people would be wrong.
It’s science.
HTH 🙂👍
