Level 4 Red: 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 red (.6) reflect is the most intense and vibrant. It adds a pure red undertone creating striking, high-personality results. Requires frequent maintenance as red is the pigment that fades fastest.

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

Questions about level 4 red

Brand equivalences

Each brand uses its own naming system. For example, a level 4 red is 4R in Colorance, 4RV in Color Gels Lacquers, 4RR in Chromatics. 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.
