Nice colour, you found for your sprinter.
I´m considering what colour mine shall have. It shall certainly not stay white, though it is very practical when travelling in warm climates.
I have first been thinking of painting it navy grey, but recently I have thought of painting it a light olive colour. Not too dark and not too army looking, but a warm enough colour to fit into nature.
I like yours very much, and you are right; it looks good with mud on

, but I think it will be to dark for travelling southern France in summertime. So maybe a couple of tones lighter.
Is there an official colour code for your colour?
The colour of the one, on the attached picture is also a possibility.
