I’m so sorry for the slow reply, I wasn’t getting most forum notifications since switching laptop, so am catching up on everything now.
Regarding your question, unfortunately not. But I can’t think of any reason why this shouldn’t be possible (though I will have to check the code). And I do appreciate that some people prefer working with that format. That’s why MT has an option for reporting color values as hex’s. I’ll update you in the next few days.
