I'm biased, but I've yet to see a colour scheme better than the 2016 Boardman Pro Carbon:

The colour schemes on the subsequent Boardman ranges have been uninspiring at best and were a major factor in me buying the Giant, which also has bright green detailing:

That said, Giant appear to have gone down the same route since.
Both bikes have green dust caps as well, just to set things off nicley.
The Giant replaced this Boardman Road Comp which had a fantastic "liquid mercury" paint job which really popped in the sunlight:

It originally came with white bar tape, which looked fantastic but it was impossible to keep clean.
The Raleigh Amazon I had in the 90s also had a great paint job - I've never seen as much metallic flake in a finish. The base colour was green, but the flake could make it look different colours depending on the angle you looked at it from.
FWIW, I also have a pearlescent orange car (with orange dust caps)
