This is a really fun way to look at it. I don't think I have a signature color or colors. I like the idea - it sounds so classy and calm! - but I enjoy too much variety.

If anything, I have a signature palette: Medium-toned, cool but saturated blues, pinks, and greens thrill me. For blues, royal, cornflower, sapphire, columbia, etc - lots of the collegiate blues. Not too light, not too purple, not too gray. I also love medium pinks, like watermelon, rose (not dusty), and strawberry; not too purple nor too peach. For greens, apple, leaf, grass, and bottle green; but the bluer greens like jade and mint and pine have been growing on me. The right greens are hard to find so I don't have as much as I would like in my wardrobe.

I think most people would who see me on a regular basis would say stripes are my signature color.

I tend to gravitate toward the same colors over time, regardless of trends. Deep purples, darker solid greys (not so much heather), black, blue and turquoise. Colors I used to love but have broken up with include espresso/chocolate, lime, periwinkle, and all shades of pink. (Guess I'm finally over the nineties?)

I love red as an accent color, but as others have said it needs to be a cool, true red for me, or a deeper muted red with blue tones in it. I don't enjoy wearing colors with too much orange/yellow in them. So I don't really have any coral, lime, camel, tomato, rust, etc. I wish I had more green right now, specifically true evergreen and emerald shades without any olive/brown tones.

Though not my best colors, I do have a soft spot for mustard and olive, and like to pair them with bright and/or saturated winter colors (turquoise, cobalt, navy) to make them work with my palette and not get orphaned.

Although I don't take seasonal color analysis as gospel, it has definitely influenced how I analyze color in my wardrobe, and helps limit my impulse purchases!
