Tunsgate Green anyone ?

[WGHBirmingham]

I was wondering if anyone has any experience of using the Farrow & Ball colour Tunsgate Green ?
My 7 year old DS wants his bedroom painted green, however it's a very awkward shaped attic room, with the ceiling sloping down to form quite a lot of the wall. I therefore thought it would be a good idea to paint the ceiling and walls all one colour to try and stop it from looking bitty. However I don't want a bright green ceiling, so I'm looking for a pale, subtle green to use ( but something that would still appeal to a 7 year old ). Thought Tunsgate Green might be a contender, but I've just seen a picture of it online where it looked a bit dayglow yellow.
Has anyone used this or can they suggest anything else. ?
Thanks for your help.

If you use the same colour on the ceiling as well it will close down the space and make it look and feel smaller.

How about a compromise with your DS and painting the largest wall green and accessorising in green while keeping the rest of the walls lighter and the ceiling white? That way it won't look bitty, but neither will it look like an oddly shaped box.

I have used tunsgate green and it is neither dayglo or yellow. In a similar attic room I used James White.....barely green though.

Ds has a similar oddly shaped attic room. He wanted it blue. I quite like that the ceiling is white. The blue and white look well together and the shape gives character to the room. I don't think I'd like the ceiling the same!e colour as the walls. It could feel like the walls were caving in.
