Sorry, don't have a picture.

But I've seen both Avus Blue and LeMans Blue E39 M5 live (not at the same time though) and all I can say is that those colors are definitely very close to each others.
Lemans might be very very slightly darker. My feeling is that Lemans has slightly more red in it making it feel like more "electric" and aggressive in my opinion. Anyway - both of them are absolutely stunning!
