Colour board - blue and green

I have put together another colour board because I enjoyed doing the other one so much. This combination is blue and green. I love the colour of thistles with the rich blue and bright green at the tips. These colours go together naturally and are really fresh, I think they look particularly lovely against a natural wood or stone as in the two images shown.

The paint colours are from dulux (first two) and farrow and ball (second two), names as follows from left to right:

Grecian Garland 1, Kiwi Burst 2, Cook's Blue, Pitch Blue

Where would you use this combination?
