I would stick with the natural white for cabinets... if your wanting white again.

I would be more concerned with how those two cabinet colours work with your wall colour and concrete palate. I think one will be more favourable than the other if you can put samples together. Also keep in mind what lighting you'll be using. Since if you have cooler colours then 'cool white' 4000K lighting will look best, likewise if you have the warm Alabaster colour then 'warm white' 3000K would be best.

I understand where you are coming from. Had the same dilemma when we built our house. We ended up asking the tradies for the whitest of whites with all of our finishes as we felt that it would make it easier when choosing soft furnishings. Our builder used Wattyl products, so I am guessing that the Dulux equivalent would be the 'white on white'.

Laminex and Dulux got together and have colour matched their white palettes. For example Dulux snowy mountains quarter matches the Laminex. White Linen. The lexicon Dulux paint goes with polar white Laminex. Go onto the Laminex web site and check out the colours. We did a kitchen in Laminex Polar White silk finish, the Chalkstone tops and Lexicon quarter paint with a grey oak flooring and Kit Kat tiles which worked well.
