Hiya
I have pulse in caymans and yes it is a new colour but not available in the uk yet as far as i know? It's an orange/red colour a bit like a blood orange, another new colour is mango which is a pale bright orange.
Myself and Sheltie crocaholic have put pictures up on here of the new colours as we both have them.
Look on Taylorshoes.com, if you order any ask them to mark as a gift as you may get charged export duty which is about £16, i normally order 2 pairs and some jibbitz as if you buy just one pair you don't save any money due to the delivery costs. They are very efficient and you can track your order on line too.
You can also try ebay, there wasn't any when i last looked in these colours but items get added all the time.
Good luck
If you have any more queries just ask
Kay
