Someone asked this awhile back:

“I have a huge question that I have heard various views about in color analysis. I am wondering about childhood coloring vs. adult coloring? These twins for example look like they would have been different seasons as children than they do as adults. I have seen people who seem to have very different coloring than when they are smaller and it makes me wonder if season can change? What do people think about this?”

Here’s both sides of the argument:

YES

“Do Personal Colors change? I have a new hair color now and I think I might need a new palette.”
“Personal colors can change if your hair color is new or different. Also, although we remain basically the same throughout life, with age your colors may soften and lighten. In these cases, a new color palette is a great idea.” Rose Ann Woolpert

“Age alters your colouring. With Seasonal Colour Analysis, we were told that once your colours had been determined, they would never change. You only need to look at photos of people when they were 18 and 60 to see the dramatic change that occurs to skin, eyes and hair colour over time. As your colouring changes, your colours need adjusting.”  Image Innovators

“Will My Season Change If I Dye My Hair/Wear Color Contacts/Tan?”  Yes, but within your own season (eg. Winter, Spring, Summer, Autumn) or your color palette’s ‘sister group’ (eg. Clear Winter and Clear Spring). Some women may notice that when they dye their hair lighter they can wear lighter colors.” Chic Fashionista

“Age causes your hair to gray, skin tone to become cooler and lighter, and your eye color to lose its brightness. You’ll notice that you look better in cooler and/or less intense colors than the ones you wore when you were younger and your coloring was brighter and had more depth to it. Less intensity – cooler color palette This results in moving down on the intensity scale of your personal coloring. You basically have to determine your seasonal group based on the colorings you have now. Based on the description you provided I would say you are now a Cool Winter (blue eyes, ruddy-fair skin and salt & pepper red hair). However, if you have a lighter shade of red hair color, you may now be a Light Spring, and as your coloring gets cooler you may turn into a Light Summer.” Chic Fashionista

” Age will change your coloring – With seasonal analysis you were told that the same band of colors that suit you when you are 18 will still suit you when you are 80.- Not True! Everyone gets cooler and paler with age. A warm person looks cooler as they age and like the late Queen Mother who was a Spring in her youth (as was Queen Elizabeth) had cooled into a Light Summer in her old age.”  source

“These days we know that there are 6 main qualities that you might have in your coloring: Light, Deep, Warm, Cool, Clear and Soft. Once you find your dominant characteristic, you are well on your way to finding your best colors. Depending on the time of year and your level of tan, you may flow between the seasons of your dominant characteristic.” Leave Me To My Projects

Steiner says we do change from childhood   The temperament you were when you were a child changes when you become an adolescent. “…the Sanguine turns Phlegmatic, the Phlegmatic turns Melancholic, the Melancholy turns Choleric and the Choleric turns Sanguine.” In other words, the temperament refines. Your secondary is often correlated with the type of one or both of your parents. Your temperament as a child may become your secondary as an adult.

Though not directly correlated because it’s about MBTI: 
“Jung believed that all the functions are largely unconscious and undeveloped in infants. As we grow and develop, the different functions develop. The timing of this development has been the subject of considerable study. It is generally believed that the dominant generally develops up to age 7, the auxiliary up to age 20, the tertiary in the 30s and 40s and the inferior or fourth function at midlife or later.” source

Callaway says Caygill says we get softer.

Jennifer Butler moves people around between seasons, but also talks about someone being a certain season by color and another by personality.

NO

“People often ask if our patterns change as we get older. They do not — your color pattern is genetic, and as unchanging and unique as your fingerpint.  However, although the pattern is constant, our personalities and our physical coloring do tend to tone down with maturity.  If, like Picasso, you go through a ‘blue period,’ this is an indication of a specific psychological mode, which you may be in for several years.  You will come through it much more positively if you ensure that the blues you choose are in the right tonal family for you.  Children tend to prefer the stronger, brighter end of their spectrum. Often when a woman finds that there are colours she used to wear which she simply cannot get away with now that she is older, she assumes that her colouring has changed.  The truth is they were never good colours for her. Harmonious colours make us look and feel younger, healthier and less tired — but when we are young, we can get away with negative colours because we are younger, healthier and less tired.  If a colour is right for you, you can wear it any time of day or night, with or without make-up, from the day you are born to the day you die.” Wright

“Your undertone is fixed and determined by your genetics, and is shared by all your colouring including your tan. Your Season doesn’t change with a tan, though you might have different colour preferences, for the higher contrast with the lighter choices, for instance. Many Bright Winters can find black too severe or their coolest colours too shadowing, and a tan might change those tolerances enough to feel more comfortable. When you’re tanned and look warmer, the undertone might seem warmer. Whatever undertone means, it doesn’t mean ‘overall feeling and effect’. This is one of those “It looks warmer and feels like it should be warmer, so therefore it is warmer.” conclusions that are not necessarily sound. Even pure cool Seasons can tan very golden looking. They look more yellow, but when their colours are tested, it’s still the same cool yellow their genetics always produced. They may have more melanin, which contributes red, brown, blue, and/or black, depending on the type of melanin, but it’s the same colour of melanin that it always was.” 12 Blueprints

“When your hair color changes, does your Season change? As we age, we all will get gray hair. Does that mean we will then all be a Summer or Winter, as assumed above? NO. Your complexion fits into one of the Seasons. Your hair coloring may make you look somewhat like another season, but your Season remains the same. If you’ve been given the right colors they will look good on you for the rest of your life! Take a look at at the pictures below. They are all gray haired individuals and they are all different seasons.” Color Me a Season

“The skin undertone is determined by different elements, namely hemoglobin, carotene and melanin. The composition of these 3 pigments is defined by genetics. This means that the composition will never change during a lifetime. Skin color (or skin overtone) can change due to a number of factors, such as exposure to sun, illness, blood pressure, etc.” New Start at 40

“Skin color, rather than hair or eye color, determines a person’s season. Bernice Kentner warns, “Remember, do not rely on hair coloring to find your Season!”[13] While hair color may change over the years (and hair or eye color may be artificially changed by dyeing and colored contact lenses), the person’s color season will not change.” wikipedia

“Your hair color may change over the years, but your color category at birth remains the same throughout your life. Your skin may deepen with a suntan or yellow or fade with age, but you will always remain the same seasonal color type.” source
