Level 1 Natural

Each brand uses its own naming system. For example, a level 1 natural is 1N in Anti-Aging Permanent Liqui-Creme, 1 in Evolution of the Color, 1N in LumiShine Permanent Creme Color, 1N in Permanent Color, 1 in Color System, 1 in Majirel, 1 in Dia Light / Dia Color, 1 in INOA, 1N in SoColor Pre-Bonded, 1N in The Color XG, 1N in ChromaSilk, 1-0 in FACTION8 Permanent Color, 1NN in Color Gels Lacquers, 1 in Revlonissimo Colorsmetique, 1 in Salermvison, 1-0 in Igora Royal, 1-0 in Igora Vibrance, 1-0 in Igora Zero Amm, 1N in Color Charm Permanent Liquid, 1 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.
