Final answer:
Lowlight formulas using Shades EQ should utilize darker tones from the value scale to add depth and contrast to the hair. Value, which is the relative lightness or darkness of a color, guides the selection of shades. The goal is to create a natural-looking gradient and dimension in the hair.
Step-by-step explanation:
Lowlight formulas using Shades EQ should be aimed at creating contrast and depth by using tones that are lower-keyed, or darker, compared to the overall hair color. Value plays a significant role here as it refers to the lightness or darkness of a color. By adding more of a darker shade (low-keyed value) or less for a lighter shade (high-keyed value), hair colorists can achieve the desired gradient of color and add dimension to the hair.
It is like having a value scale at your disposal, where you have pure white on one end, black on the other, and varying shades of grey in between. Hence, for lowlights, the chosen Shades EQ formula should consist of colors that are on the darker end of this scale. This technique provides the artist, or in this case, the hair colorist, with the palette needed to create visual depth and rich, nuanced hair colors.
