What strong colour wall near this heavily patterned paper?

I'm going to have this on my stairs wall.
I've opened out under the stairs, and want to paint in there. It's only a few squares metres as it has an external door under stairs now too. Area is fairly light for under stairs. Opposite wall is pale grey.

I want a strong colour, taking something from the very wide choice on that wallpaper, but I'm stumped!

Opinions would be very welcome please!

I prefer to avoid teal as I have that in lounge, and lime/apple greens as that's it kitchen. Love orange but don't want to look 90s terracotta and also might, with the kitchen, be a bit too citrus.

I'm leaning towards yellow... (yellow and grey, hello 80s!)

The floor is oak, if that makes any difference!

Purple.

Can you make that a clicky link?

Jesus! That's amazing

I'd say an off white... Not cream toned, just not pure brilliant white.

How's that for clicky?

Ooh, lovely! Personally, I'd go for one of the new-plaster-like pinks.

I'd go for a blue, but may not be strong enough for you. I think it would look nice with the grey.

Ooooh, thanks Sandthorn for doing the clicky for me!

And thanks everyone for the suggestions. Food for thought.

I have a feeling the wall will be painted more than once!

I'll post a photo when it's done - the wallpaper ain't cheap, it's my birthday present to myself

Loving the wallpaper OP

It's lovely isn't? Will definitely post a photo when I've (saved up enough) to have it done

grey. with wallpaper like that you don't want something that's going to fight for attention.
