"Zyla uses the romantic colour to determine season. Zyla does it more by the properties of the colour than its temperature, so you need to keep that in mind. So his Spring is Crisp and Clear (Barbie doll pink, cool dusty pink, carnation, peach coral, light orange, clear red and he has more....), his Summer is Cool and Relaxed (rose pink, raspberry, strawberry, watermelon, burgundy, cranberry, and more...), his Autumn is Warm and Mellow (salmon, deep apricot, burnt peach, Christmas red, cayenne, cinnamon, rust, and more...), his Winter is Rich and Contrasted (ballet pink, shocking pink, poppy, fire engine red, cranberry, rusty brick, port, cherry). Notice that cranberry shows up in Summer and Winter. He's also got Tangerine under Autumn, when most people would consider it a Spring colour. And he's got Brick tones in Autumn and Winter. So I think the key for Zyla's system is to notice the properties of the colour. Only for Summer and Autumn is he particularly concerned about temperature"
