Romping is almost a duo chrome. It looks like Accent Red pigment. It is a frosty magenta with a blue-violet shimmer. Passionate is a matte red shadow.
Moonflower is a muted, dusty blue color. It is a cool color. Big T is a true blue-green color, along the lines of Waternymph, Teal pigment, A Bluer Blue, and Blue Absinythe. It has warm undertones. Moonflower and Big T are very different. HTHS!
