.....and here is that night fighter Hurricane:
As Tom said the base colour was RLM 66, not my idea, I saw it saw it over on Hyperscale on a Cr42 nightfighter, with the panel centres in a lightened version of the base coat, and the panel edges in a darkened version of the same.
Looks complicated, but isn't, and to my eye at least, looks more like a 'scale' black.
