Pictures of hair colors on your screen are only a guide at best. For perfect color matching, mail us your sample. These are the main colors, but there are many more that we use for matching client hair samples exactly. The lower the number the darker the color, so #1 is jet black and #60RY is white. #ash4 and #ash7 are ash colors, (more green/cool). The others here are all natural tones besides #22R which is warm/redder. There are many warm colors (ending with R) not shown here because they are rarely used. Again, the only way to get a perfect match is to mail a hair sample.
