I couldn't do anything with this. I must be in the middle.
I think it said I should wear chokers, but I usually hate chokers because I like to wear scoop neck or v neck tops. They make me look taller. I like to fill in the neckline with a v shape.
I love all 3 colors of metals. Rose gold tends to disappear on my skin, but sometimes I like rose gold the best. I have found other ways to make it show up: a sparkly chain, a mop inlay, two tone jewelry. Sometimes it's nice if the bigger pieces are more subdued.
I have heard that EVERYBODY looks good in coral. I don't know where that was coming from. Blue (including turquoise) and coral are my best non-neutral colors. Orange, yellow, red, lime green not so much. So maybe I AM cool-toned. But brown is really good on me, and browns are darker variations of orange, yellow and red.
I don't think you can categorize too much. I think everyone could have a custom color palette. There are veins, skin tone, hair color and shape, eye color and shape, smile shape, personality, lighting, posture, proportions, makeup preferences, clothing preferences.... Just try all kinds of things on, look in a full length mirror, and see how you feel. Or have a color consultant or stylist advise you based on your specific characteristics.
My most recent jewelry purchases included all 3 metals and were totally about how the pieces made me feel. I didn't want to take them off.
