Shed colour?

If they have tester pots, it's worth getting a few and checking how they actually look on wood when you've given it a couple of coats. For instance, the Fresh Rosemary is the same kind of colour but a bit lighter.

 

Markymark - good choice I'd say. I'm a bit late as you've already decided but was going to suggest a green too
I bet it looks fab! look forward to the pic once done.

 

Yes ... it is MUCH more than coloured water. I couldn't believe the recent prices either! Bought a spare 5L tin from Travis Perkins the other week for £9 but the first one I bought 3 years ago was quite a bit more than that as I recall.
Pic is from one coat applied 3 years ago and it has served me well ...
May need a little touching up here and there but I've been more than happy with it I must say !
