Pravana ChromaSilk organizes shades in a hybrid format:
- Naturals: Level + N (5N = light natural brown, 8N = light natural blonde)
- With reflect: Level.Reflect (6.1 = dark ash blonde, 7.4 = medium copper blonde)
- Reflects: .1 = ash, .2 = beige, .3 = golden, .4 = copper, .5 = mahogany, .6 = red, .7 = violet, .8 = pearl, .9 = smokey
- Blended neutrals: NT (7NT = neutral blonde, 5NT3 = light neutral golden brown)
ChromaSilk features silk and keratin technology for extra shine and softness in the final result.
VIVIDS does not use this system. They are direct dyes: they go by colour name (Magenta, Wild Orchid, Blue Topaz) because they have no level and no reflect. They are applied without developer over pre-lightened hair, so the result depends on the starting level, not on a number from the chart.
