Base Color for Haircolor
Q: How can I know which colors have a blue based color or a violet based color?A: Generally speaking, when you buy your hair color and developer separately at the beauty supply stores, you can simply look on the bottles of hair color and see what the base color is for the color formula.
A good way to help sort things out is to look for keywords that will help you determine the base colors of the hair color formulas you see on the shelf.
For example, if your color choice is described as cool, then the odds are that it is using a blue, violet, blue-violet, or even red-violet base color, while warm tones often contain red, orange, red-orange and gold base colors. Neutral colors generally use "neutral" color enhancing tones and maintain a cool/warm balance.
Often, you can get help in determining the base color of a hair color formula by checking the product website. Clairol, L'oréal, and other manufacturers offer online "swatches" and color charts that describe the base color of their product lines. These make a good source if you are looking for information and can't find it from the product packaging or the labeling on the store shelves.
