I'm surprised that there are not any Healeys - at least that I have seen - in this spectacular and stylish combination of original exterior and interior colors, although very nearly never seen together:
Healey Blue paint with a red interior. I'd likely also go with a red top and tonneau, or at least a red tonneau.
For potential future buyers, you will have used an original paint color and so the car doesn't need to be dismantled to the last nut and bolt to undo an odd-ball paint color, and someone with a "less developed sense of style" can easily change the interior to the dark blue that would be "normal" with Healey Blue paint.
I've alway felt that metallic Healey blue was THE signature color for Austin Healeys. Healey practically owns that color. It's seldom seen on other British sports car makes and to my eye, looks wrong when it does, with E-Types the possible exception.
I don't know if it's the most popular, but I agree with nevets that Healey Blue has to be the signature Healey color Something about that metallic color just highlights the curves of the Healey perfectly (and I may be a bit prejudiced, too). As far as Reid's color suggestion goes, I think it could be striking on a 2-seater like this Cobra, but probably that red would be way too much on a 4-seater.
