Take a door off and head to Bunnings. They'll colour match and tell you the closest paint colour.

Hi Michelle, There are many independent designers (both kitchen & interior) that would be happy to put together a colour schedule to suit the kitchen design that your cabinet maker has prepared, so a few phone calls in your local area should have this sorted for you. Alternatively, we offer a cost effective 3D rendering service at The Interior Difference (check out the examples on our Houzz profile) customised to your colour selections to assist you in ensuring that you have made the right selection before you commit to the colours. We find this is really helpful for client's who have a good idea of what they think they want but just need a visual to give them the confidence to proceed. Feel free to send us a message if you have any queries. Good luck with your project!! Rebecca - The Interior Difference

Hi. If this could be of any help, you can go on Caesarstone website and select the stone you have chosen from their list (Frosty Carrina) and check the page. On their website, they have lots of examples of kitchen/bathrooms etc. for each stone colour, usually at the bottom of the page. This may be inspiring.
