Küül Color System Color Chart

Browse the full Küül Color System range in one place. Küül is a permanent hair color brand widely used across Mexico and Latin America, with a broad chart from black to lightest blonde and complete reflect families.

Küül uses a dot notation to separate level and reflect: 7.44 means level 7, intense copper. Natural shades are written as a single number (1 to 10).

Note on reflects: in Küül, .2 is pearl/iridescent (with a violet cast) and .7 is violet, unlike other brands. Do not assume the rest line up with other brands: in Wella's key /4 is red and /6 violet, and in Igora -4 is beige and -6 chocolate. Check each reflect before converting.

Küül numbering system

Küül Color System organizes shades as level.reflect:

  • Level (1-10): Color depth. 1 = black, 10 = lightest blonde.
  • Primary reflect: First digit after the dot. .1 = ash, .2 = pearl/iridescent, .3 = gold, .4 = copper, .5 = mahogany, .6 = red, .7 = violet.
  • Secondary reflect: Second digit after the dot. For example 7.64 = level 7, red (primary) copper (secondary); 7.44 = intensified copper.

Named shades (Chocolate 5.31, Mocha 5.45, Latte Macchiato 7.31, Cappuccino 7.35, Burgundy 4.65) are blends of brown and mahogany reflects from its fashion line.

Note: Küül's reflect key is its own — no shared standard exists across brands. Its .2 is pearl/iridescent (violet), unlike Wella's /2 matt; its .7 is violet, unlike L'Oréal's .7 matte. When looking up equivalents, use the shade name alongside the code.

Color System equivalents in other brands

One shade per level of Color System with its closest equivalent in other professional brands of the same type. These are orientative matches calculated by level and reflect: every brand uses its own pigments and bases, so always strand-test when switching.

Küül Color System Color Chart

Everything you need to know

The first number is the level (1 black to 10 lightest blonde). The digits after the dot are the reflects: the first is the primary reflect and the second is the secondary. For example 7.44 is an intense copper blonde (level 7), and 7.31 is a golden blonde with an ash cast (Latte Macchiato).

Küül uses .1 for ash (anti-copper) and reserves .2 for pearl/iridescent, a reflect with a violet cast that neutralizes yellow bases in high blondes. That's why shades like 7.22 (intense pearl) or 10.22 are popular after lightening. The .7 is violet (6.77, 7.76); in the converter it groups with pearl/iridescent because of their shared cool cast.

Küül mixes with Küül peroxide, at the ratio in the brand's technical sheet. Choose its strength for the service (tone-on-tone, gray coverage or lift) from the manufacturer's directions.

Yes. Küül Color System is a permanent color with gray coverage. For resistant or abundant gray, reinforce with the natural tone (.0) of the same level and follow the brand's ratio, developer and timings.

Küül writes level.reflect with a dot, but its reflect key is its own, so an equivalent is not a straight copy of the number. Use our hair color brand converter to find the equivalent of any Küül shade in Wella, Igora, Matrix, L'Oréal, and more. For precise formulas with your salon's brands, access Blendsor.
