My little grandaughter has hair much like the picture posted by Frankiz but I don't see that color on Rusalka's chart. The color on the chart seems dull and lifeless. If these colors were on boxes of women's hair dye, it wouldn't sell. On the other hand, my hair is dull and lifeless but I going grey and I am an old man.

Nothing artificial can look like genuine human hair and these samples are probably some sort of dyed synthetic material. Like I said, there are almost endless amount of color possibilities when it comes to real people because almost everyone has at least two or three different shades of hair on their head which makes our hair look much more vibrant and more 'real'. As for the chart, I've seen better and more detailed color swatches in hair salons but this was the best I could find online. They're either of very bad quality with all the colors distorded or stamp size images for a whole chart. I'll post some more examples if I come across any. We could also post photos of random people whose hair is of a certain color -preferably not dyed.

Here's some information about how we get our hair color. I highlighted the parts about how different colors come to be and how there are different shades of the same hue in one person's hair.
How do we get all these different hair colors and shades Basically, the natural color of the hair is decided by, what type of melanin is in the hair, how much melanin is in the hair, and how densely packed the melanin is within the hair fiber. So black hair is the result of a very high production of eumelanin which is very densely packed into the hair fiber. Brown hair comes in various shades and richness of color but basically brown haired people have a somewhat lower density of eumelanin in their hair fiber. The warmer, richer tones of brown hair are due to a greater presence of red - yellow pheomelanin. So the relative quantities of eumelanin versus pheomelanin in brown hair increase the heterogeneity of brown colored hair. Blonde haired people have eumelanin in their hair fiber as for black haired people, but the eumelanin is present at a very low density. Plain blonde hair is predominantly eumelanin while richer honey blonde hair has relatively more of the yellow red pheomelanin present. Red haired people have a high density of the pheomelanin pigments in their hair fiber. Those who produce virtually no eumelanin have a red to orange color depending on the density of the pigment in the hair fiber. Red haired people who have a greater relative proportion of eumelanin production have a deeper red to red brown color. Gray hair is essentially the result of reduced pigment production. The contrast between the hair with more color and the hair with less color, causes the appearance we call gray hair. With so many different factors influencing hair color you might also be able to perceive why each individual may have hair fiber with different shades of the same basic color. Not all hair follicles are created exactly equal. While in one hair follicle there may be a little more eumelanin production or may pack a slightly higher density of melanin into the hair fiber, the hair follicle next door may not be quite so efficient. So when looking at individual hair fiber colors everyone sees some slight differences in the shade. So long as this variation is evenly distributed across the scalp we perceive one overall color when we look in the mirror. Only when a distinct area of follicles start producing more or less pigment do we identify that region as being a different color to the rest of the scalp hair. Overall then there are many different interactions that lead to the subtle and not so subtle differences in hair color. Anthropologists and forensic scientists are most interested in this area and try to compare hair color between genetically distinct population to find identifying traits that can be exploited in their respective fields. |

About why people's hair darken with age. It's those tyrosinase Dr. Solar Wolff.
Eumelanins are very strong, stable proteins made from tyrosine. The large eumelanin biochemical structure is formed by processing the amino acid tyrosine into dopa and dopamine and connecting several of these molecules together to form eumelanin. The key enzyme in this process is tyrosinase. The more tyrosinase activity the more eumelanin is formed. This is one method by which different people have different shades of brown to black hair color. More tyrosinase activity results in more pigment production and so a darker hair color. As we get older, tyrosinase activity increases. It is most active in middle age and thereafter tyrosinase activity decreases. |

Well, finally, I found it. Now I know the proper description for my hair colour.

That's my dad's hair color when he was in his 20s. Dark strawberry blond. He now has dark auburn/chestnut hair in his late 50s. Hair also darkens much quicker if you keep cutting it, I have observed.
