Where to buy custom color paint?

[Kismett]

I’d really like to get my hands on some Hague Blue but not true Farrow and Ball because we are looking for something more durable. I’ve heard that Valspar isn’t great paint and I wasn’t impressed by the colour matching at B&Q when we tried it before. Is there anywhere else I can go? Or order online?

We found a local hardware that made us a discontinued Crown shade. Google local and ask!

Johnstone's decorator centres are often recommended on MN. I believe they have codes for their machines to replicate F&B colours.
