3 shades of green paint?

[Elspeth7]

I planned to do my bedroom a sort of sage green. We bought curtains and took them to a paint shop to be colour matched. The idea was to have one feature wall the same colour as the curtains, then go a shade lighter for the other 3 walls. Today I painted the feature wall and it's lovely (spruce shade on pic). Then I started the cutting in with the lighter shade (blue shamrock), but it seems like it's too strong a colour, and possibly it's a little bluey as well. Although it is from the same palette (see photo) so it shouldn't be, it could be just the light at this time of evening. I could finish this wall since I've started it, then maybe go another shade lighter for the last 2 walls. Would that be nice do you think? Or is 3 paint colours too much? They are all on the same palettte so they should all tone.

I'm having trouble reading the labels. Is it Johnstone Dwarf Spruce on the feature wall?

In any case, 3 colours would be too much, imo. A feature wall is supposed to draw the eye, and if you had two other colours competing, it would defeat the purpose of the feature wall.

Blue Shamrock doesn't look too strong on the card. But Coastal Cottage looks a very nice shade. Maybe that would work better in the room for you.

No it's the 3rd one down, spruce shade on the feature wall. Then the next one ðown blue shamrock that I bought for the rest. They're definitely darker than they look on that card unfortunately.

It could be the way light hits that wall, paint not dry, or not enough shade difference. Hard to say without a pic.
It is only one shade difference, you might find you get the affect you want by shifting two shades or even three. Like pp I can’t read the colour names as they are upside down, but the one that has Cottage in the name. They do look slightly bluer as the colour gets more pastel though, so paint a sheet of paper and tape it up to see how they work.

Personally I don't think it'll age well. Boldly coloured paint can look shabby quickly in my opinion and also end up looking like a toilet.

I would choose a very very pale shade in the colour range (like Very pale sage tinged white) and paint that on all 4 walls. Then use a accessories to tie it all in.
