Is this warm?

[lilmishap]

I've accidentally picked a bad colour, I didnt study light differences enough and have North and East light as well as South from back door through half the room. The end result is that I now know I'm not scared of dark colour. I love the back wall (much darker than it looks in photo) but the chimney looks like kiwi after 4 coats. They are the same paint. If you know a fix for that (or a green that matches the back) please tell.
I've fallen for Common Dormouse but I don't know if that is warm or not as it looks grey and browny. Grey-y grey looks crap in here.

I don't trust my own eyes right now because the kiwi green I didn't expect has thrown me.

It's the Third image I'm asking about!

Only two images ?

I’m not entirely sure why it matters if the colour is warm, or cool, but I’d say that the colour you linked to is a warm-ish neutral.

I think that when you have different light conditions on different walls, a darker colour is always going to accentuate that. The only way to fix that is to change the lighting, so that the space is more evenly lit. Or use a lighter colour.
