Sourcing blue airbricks

[Lower]

I need 2 off 9 inch by 3 inch blue airbricks to go under a set of french doors we've had fitted to improve the subfloor ventilation. I cannot find them anywhere. I can find red or buff, but not blue.

Any suggestions?

Seem to be available Midlands area only?, you can do as Ronny said and paint them.

Only plastic unfortunately. I'm looking for clay.

I've had to put in the buff one and i'm going to paint them dark blue. They're under a french door set so not to visible under the step thankfully.
