I really hate the various 12 season color analyses. I think they're limited (get rid of many useful colors) and inaccurate. What they reflect accurately though is that the original color schemes are very broad - too broad for most folks to look good in all the colors.
I like the Zyla system where you look at your body for your colors. When I did that, the colors that I am naturally drawn to really popped out at me - and some of the "why do I bother" colors fell off my radar.
When you're looking at the colors that are your very best colors, all the colors should work together. I pulled these things from my closet today - I made most of them, but over the course of over two years. Notice how all the blues and the greens blend together, and the red and the peaches/pinks are so similar that you can hardly tell where one garment stops and another starts.
And that's how your real colors work - you can hardly see where the groups of colors change when they're all together. All of *your* greens have about the same amount of yellow or blue in them... and the other color just gets a bit more intense (green is blue+yellow). Like I wear greens from a just-a-bit blueish green and you add blue until you end up with a bright navy. (Never a grey navy for me, although you can jump the other side of that rainbow and add a touch of purple to get midnight blue, which is nice). So you ask me what color of pink I wear, I say, "warm pink" - and I do. From a fairly light color all the way to geranium red (which is a clear warm red with a pink cast), warm pink is me. Which warm pink? Um. Yes?
I can wear blueish greens or clear greens that don't have a blue-green note - but I don't wear them near my face. They harmonize with my colors but they aren't in my CMB season - and they don't look good on me. Or at least they don't look as good on me as "my colors" do. I'll use them as a neutral sometimes though - I find that a pine green looks wonderful as a skirt or in a print. (Not surprising - pine green with all that pink and red and ivory is *very* floral, and flowers are my friends).
Neutrals and the Zyla system are interesting. For instance, he claims that the darkest color in your hair is a good second-base neutral for you. For me, that's darkest brown. Um. No. Brown browns me out - my skin looks muddy and I look boring in brown. But that's how I roll for all the neutrals, excepting bright navy (which is honestly more of a color than the grey-navy or black-navy that we see as neutral). But - when I look in my wardrobe, I find that I have purses and belts and shoes in that warm dark brown - and that they look awesome. So what is more important - following something else or just giving a listen and seeing how true it is? B! (I've opened my eyes to perhaps someday owning a skirt or vest in that shade of brown - I think it might be nice. But I still hate flat-brown-dye, so the perfect shade will probably be a long time in showing up.) (All of the same commentary here goes for the golden-wheat tone that he calls my casual neutral, although it muddies me up less than dark brown and I am more likely to wear it as a jacket).
The various 12 season systems say that people who wear my extreme colors can wear black. Not true! I don't look good in black, even as an accessory. It's far too harsh for my coloring, and I look out of balance. It amps up my bright colors, where I prefer to ground them. (I thought I could wear black away from my face until my MIL took a picture of me in my favorite green jade shirt and a black pair of pants. Ugh.) What color is "my black"? Charcoal grey - and that's the darkest color that belongs on my body.
So I know what my very best colors are (I have a pinboard for my colors)... but what about colors other than blue, green, pink, red and ivory? Can anyone wear any color? I think we can. I think there is a shade of all the colors that looks at least okay on everyone - but I'd like to see us make a difference between our top tier colors and the second string. Zyla helps you nail your top tier - CMB can help you find your second string colors. Should you buy a blouse in the second string colors? Err... maybe not. But it would look nice in a print or an accessory. (If I was a proponent of disposable clothing I'd say, "go for the blouse" but frankly I've gotten rid of too many second-string colored shirts to encourage you to buy one).
And then we start talking about how our personality affects the colors we choose. I like my top tier - but I like them soft and grounded. Romantic and natural, in other words! I bring in pine green with my pink and red, which reads "rosebush" if anything does. I wear my blues and greens together, which reads "water". All my stuff is tied to the natural world, which is just how I like it. I have an autumn friend who needs bright colors and high contrast to lift her spirits - fortunately her dark brown hair and denim-blue eyes lend themselves to this - she looks great in the colors of a fiery ocean sunset. Orange and teal and brown.
Your most fabulous colors are highly individual - but you can use systems set up for "just anyone" to get there. Let us play!
