Cool and Warm Hair Colors

Hair Color and Skin Tone
One of the biggest and most common mistakes made when it comes to hair color choices is failure to understand one's own skin tone and the way it responds to hair color. In decades past, women would have "color analysis" and be classified in "seasons".
In recent years, the ideal has been the use of metals - namely silver and gold - to test for and denote a person's color palette. These classifications of silver and gold directly correspond to cool and warm palettes, respectively.
Cool palettes are generally pale of skin with little in the way of pink or bronzing to the skin. Natural hair colors for cool palettes tend toward ash-based shades and coal black all the way up to platinum blonde. Eye color is often icy blue, green, violet, or gray, with occasionally a pale brown thrown into the mix.
Warm palettes are usually ruddy and/or bronzed in complexion, and even when fair-skinned have a pinkish tone to the skin. The hair colors that tend to occur more naturally among warm palettes are chocolate browns, rich auburns, reds, and even up to strawberry and golden blondes. The eye colors for the warm tones tend to be hazel, and the many shades of brown, and occasionally gray.

Choosing Hair Color
When an individual wants a change in his or her hair color, it’s important that he or she chooses the right color as a replacement. If the skin tone is warm, such as showing off gold metals best, you want to choose a hair color from the same color palette.
To be sure of this, you need to check for the base color of the hair color formulas you want to use. If you are buying your color from the beauty supply store (where you need to buy the color and separate developer) the bottle will typically tell you what the base color is for a given shade.
Note: If you purchase your hair color from a pre-packaged kit at a drugstore or supermarket, you may need to check the manufacturer's website to view color charts that will show the base colors and palettes for the shades offered in the product you wish to use. A little investigation can help you avoid unfortunate outcomes and ensure that your new color looks its very best.

The warm base colors are typically red, orange, and yellow (gold) or combinations of these. Combining the base color with the lightness levels ranging from 1 to 10 gives a full spectrum of warm shades of color, and provides nearly all the options you might want. Such color names as dark chocolate brown, auburn, copper, sunset, bronze, golden all indicate warm tones.

If the individual has a cool skin tone – his or her skin shows off silver metals best – then a cool color palette is called for. The base colors in the cool palette are violet, blue, and green (which may also be referred to as drab or ash) and may be a combination of these base colors. Many cool colors will include identifying keywords, which may be as simple as "cool," or may include words like ash, bright, or blue.
Why It’s Important:
Some people have asked me why they have to worry about the color palettes at all, since the purpose of hair color is to change the natural color to the desired color. There are actually two major reasons to choose from the proper color palette: potential color conflicts with skin tone, and potential negative color outcomes.
When someone with a warm skin tone uses hair color that is of a cool palette (and vice versa), the two palettes can create conflict depending on the specifics of the skin tone.
But by keeping to a warm color palette and choosing light auburn, or chocolate brown, or even golden blonde, the ruddy complexion seems balanced and the whole becomes pleasant.
In the reverse case, if a person with a cool complexion chooses a warm skin tone, such as if one with pale ivory skin selected a red shade, or even strawberry blonde. The skin would appear more sallow and washed out. It takes the cool shades to allow the tones of cool-complexioned skin to be asserted.

Similar issues arise with the darker skin tones of both cool and warm palettes, with the opposing color palettes for hair color bringing out the worst parts of each skin tone and shade.
As mentioned, the other reason that choosing the right color palette is important has to do with the potential for negative color results. Just like the hair color you apply to change the color of your hair. Your natural hair color has a base pigment, and that base generally fits into the color palette you have already established.
So, say that you have dark brown hair that has a bluish-drab base pigment so it is in the cool palette, but you want to go blonder, and you select a blonde you like, only the base color of the hair color is gold/yellow. The problem you are likely to encounter is that the resulting color will be greenish.
Of course, we’ve covered the subject of color correction before, and in the case of green results, you’d need another "warm" tone to correct it, namely a red-based color. However, that gets into balancing the tones, which is a slightly different topic. As far as basics go, keeping your color choices within the same family as your natural color can help you avoid many of the issues.
