Dulux white.

[Gilesda]

Hi all.
I'm painting a ceiling with Dulux brilliant matt white, described as having something called chromalock technology. It's going on an off white colour against the white undercoat which is a bit worrying. Does this paint look off-white when wet, but then dry out white? Or have I got a dodgy tin.
I don't want to carry on and find it dries that colour so would be grateful for any info.
Thanks.

It should dry nice and white... Just think how difficult it would be putting on a second coat if was the same colour!!
