It's certainly bright. I have no idea what it would be called. You can try it. Either you will like it or you won't, you can always repaint.

That would look terrible on all four walls. You had lots of good suggestions on your previous post for better colors, but I guess you're stuck on "Kelly Green". Good luck.

Here is what Sherwin-Williams thinks it is:

I’ve always really loved this green bedroom... BM Bunker Hill Green might be close?

I used a BM color called Emerald Isle for this desk I painted. It's a true Kelly. Hard to capture the true color in the photo

looks pretty darn close.

this color looks great with white and a nice navy blue.

BM Emerald Isle

this is it on the walls

you could also do just one wall w/bookshelves, like they've done here, and the others in white

Thank you!!! These are great “matches.” Will need to sample these paints!!

For a little boy’s room, would you paint all 4 colors this color green or just 1 wall (the bed wall)? It seems to make sense to do 1 wall like if a whole bookshelf wall because clearly it is distinct, but thinking it might look odd just to do a bed wall in green with BM Simply White trim and rest of the room in white like BM Simply White? So better to just do all 4 walls in green with BM Simply White trim or do bed wall just in green with BM Simply White trim and remaining walls BM Simply White? Like white trim so wouldnt do green for trim and don’t think I want stripes or chair rail in this room. Thanks!
