Does anyone have an idea of what this green might be?

Hey Nicole2014,

I'm not an interior designer (I work in a related creative field)...but I'll still have a crack at it!

If you're going for dark greys I'm guessing your green will need to be muted so it creates a harmonious colour scheme. Either toning down the green with a touch of grey or making a shade with a touch of black.

I used the Dulux colour wall under 'Greys' and found that Domino, Pollinate Half and Pale Eucalypt are a perfect combo.

Here's a link to your original image with Domino & Pale Eucalypt swatches placed beside it:  Like  ⋅  Add a comment  ⋅  Pin to Ideaboard  ⋅  Share

So maybe try Pale Eucalypt? You may want to tint it with white for a lighter but still muted look?

Colour is subjective so you (or others) may not agree with my suggestion. Hope it helps get the ball rolling though
