Blond-Tech Blond-Tech allows you to keep the color shine and ensures that it does not turn yellow. according to the principle of the COUNTERCOLORS theory, the blue-violet pigments are distributed on the hair in order to obtain a color correction effect by neutralizing the yellowish tones. Within the primary and secondary colors there are 3 pairs of colors called COMPLEMENTARY OR COUNTERCOLORS.

YELLOW – PURPLE
ORANGE – BLUE
RED – GREEN
