Help finding a paint colour

[Nyborg]

I want to paint my bedroom lavender blue - right on the border between blue/grey/lilac. Can anyone help me find a suitable colour?

Dulux do Blueberry which has a lavender tinge.

Blueberry white I mean. Definitely looks lavender on the wall.

There's a range of paints called 'Mythic' which has a decent range of lavender hues. The range isn't widely stocked in the UK but there are a small number of nationwide stockists.
It's such a tricky colour though, I'd be inclined to take eg a swatch of fabric and get a dulux colourmatch to it.
