Hello & thankyou for your question. This paint colour is called Kingstons Rule by Haymes paints. Stunning colour & even more stunning finish when used on the haymes base. Not an ad - just an endorsement for their product!! ;)

Looks like Haymes paint is not sold in the USA:(
BTW, Your design work and use of color is very striking!

well thankyou! And yes, Haymes is an Australian paint company. Im sure some local US paint stores could look up the recipe & make it however? All the best!
