If I were in your shoes (and thankfully I'm not) and was building the Hot as a hang on the wall / show bike I would go flam red, I once had a Hobbs of Barbican in that colour and it was lovely. The downside was that the paint chipped easily.
If it was to be a rider then I'd choose a powder coat rather than paint, but still a bright sparkly colour
Yeh it’s a wall hanger / show bike
I’m also slightly ocd and if it’s not right it’ll annoy me.
I’ve got a great powder guy whose work is as good as paint. But I feel this frame deserves wet paint / enamel for it to come alive.
