By way of documenting information, since this website serves as a content management system as well as a blog, this is an update in my thinking on this important topic.
In the wonderful discussions in our Facebook Fan Club, my belief that hair colour is useless in determining Seasons surfaced in a thread about the unique Season of Bright Spring. Women often ask which celebrity might embody that colouring and I can never think of one. This is the one group for which no average appearance exists. I think of Mrs. Laura Bush, with her turquoise eyes that tilt upwards. The French actress Audrey Tautou might serve as a dark-eyed example, but she has such sharp darkness and opacity of skin that she is probably more weighted towards Winter, with a smaller fraction of Spring.
Please, if anyone is finding the jargon confusing, do ask in the comments. And if you’re a Fb member, please pardon the reiteration.
While some PCA systems only recognize members of this Season as having clear blue or green eyes, but never brown eyes, I believe that brown-eyes Springs exist, and are usually mixed with a little Winter (thereby making them Bright Springs). Since the 1980s, when 4 Season systems were more prevalent, many very experienced and skilled colour analysts believe that hair color and eye colour remain important factors in determining your Season. I don’t.
I am not here to say that I am right and anyone else is wrong. Our philosophies may diverge a little. The same could be said of any two practitioners in any field. Having your colours analyzed is still the best, fastest, easiest way of spending less money smarter and looking way the heck better.
Remember that I define Season not by how you look, but by which group of colours make your skin look as perfect, young, healthy, and evenly colored as it possibly can. We figure that out using many sets of very specially coloured drapes. When we find the set that enhances you above all the others, what we have really uncovered are the exact pigments already in your skin, in your body. When you then wear the colours you already are, you look like magic because your person and your attire is sending the same wavelength of energy to the viewer. That feels really good to be and to look at.
So, for hair and eye colour to play a factor in Season, they would have to contain the exact same pigments as those in the skin.
We know that the genes that code hair, skin, eyes (eye colour and line patterns in the iris, since those quite consistently seen together), and personality are not the same ones.
We know too that some combination of these genes often travel together when the chromosomes divide (or are transcribed together when the proteins are made, or there is some sort of genetic coupling at work), because we so often see certain traits together like blue eyes and blond hair. I think it’s scientifically reasonable to say that these genes are commonly expressed together in the individual or phenotype. If anyone knows more about human genetics than I do, I would love to know your opinion.
When I look at the people whose skin I’ve analyzed, the colours that are in the skin, and so in the colours in their colour analysis palette that the drapes matched with, contain the vast majority of eye colours (and certain Season-specific line patterns) in 80% of people. I extrapolate this to say that eye colour and pattern can be correlated to skin pigmentation, and therefore Season, 80% of the time. Since it’s so very hard to correctly identify the precise colours in eyes, that value might be reduced to 70%.
The hair colours are present in the swatch book about 60% of the time. There are True Winters with orange hair. There are Light Summers with pink-red-orange hair. Colour variability abounds, and with eyebrows even more so. This says to me that hair colours and skin colours are genetically linked about 60% of the time (or less, because picking out the exact tones that create a given hair colour is really difficult).
Character traits are consistent among people in a Season pretty often, but are predominant to the Season stereotype only about 40% of the time. Personality traits are too diluted by experience, environment, and so on. Personality is too much of a hurricane to try to figure Season with. It’s a fun curiosity.
Rachel from Truth Is Beauty also made the fascinating point that as races interbreed, the eye-skin color association should fade. I’ll make the strong point that if you have not visited that website, and you have an interest in colour, you really should. She has examples of the 12 Seasons, chosen with great accuracy and attention to detail. The information is also organized in a beautiful way.
