Salerm uses a decimal comma between level and reflect: 5,4 = light copper brown.
- Level (1-10): depth, from black to platinum blonde.
- Reflect: ,1 ash, ,2 pearl/iridescent, ,3 gold, ,4 copper, ,5 mahogany, ,6 red, ,7 brown, ,9 violet.
- Multiple digits: the first one rules — 6,74 is brown with a copper nuance; doubles (,77 ,11) intensify.
Alongside the numeric scale, Salermvison includes collection shades with their own commercial name (3,221 Wenge, 6,25 Hazelnut, 9,112 Nordic Blonde) that follow the same level-and-reflect logic.
