Is there a way to copy/use a (somewhat) shared color scheme?

I really like the 2018 color scheme contest layout submitted by @ mikechristopher called Stem. Is there a way to import or otherwise replicate this color layout? Sorry for my ridiculous question btw. …after searching these forums to figure this out on my own for the past hour, I finally succumb to asking an expert for some guidance :slight_smile: Cheers!
