All codes represent the same level (4) and reflect (ash). Chemical formulation differs between brands — results may vary slightly.

Level 4 Ash: what it means

Level 4 corresponds to a medium brown on the universal colorimetry scale (1 = black, 10 = lightest blonde). It measures the lightness or darkness of hair, independent of the reflect.

The ash (.1) reflect adds a cool, gray-blue undertone that neutralizes warmth. It is the most requested reflect for counteracting orange or yellow tones. Ideal for those who prefer a cool, sophisticated result without visible warmth.

Each brand codes level and reflect differently. The table above shows how the major professional brands name this same shade: level 4, ash reflect.

Questions about level 4 ash

Brand equivalences

Each brand uses its own naming system. For example, a level 4 ash is 4A in Anti-Aging Permanent Liqui-Creme, 4NA in LumiShine Permanent Creme Color, 4A in Permanent Color, 4A in SoColor Pre-Bonded, 4A in The Color XG, 4NA in Color Gels Lacquers, 4NA in Cover Fusion, 4-13 in Igora Vibrance, 4-13 in Igora Zero Amm, 04/12 in Shinefinity, 4A in Color Charm Permanent Liquid, 4 Cool in Yellow Color. Although codes differ, they all represent the same level and reflect.

Level and reflect equivalences are a useful reference, but not identical. Each brand has its own chemical formulation, pigments and technology. Two "equivalent" codes will produce similar but not identical results. Factors like natural base, porosity and color history affect the final outcome.

Generally yes. If you maintain the same level and reflect, the result will be very similar. However, a strand test is recommended when switching brands for the first time, as formulation differences can produce slightly different nuances.
