Chromatics does not number the reflect: it spells it with letters. 5Cr = level 5, copper with red.
- Number: the level, 1 to 10.
- First letter, uppercase: the family in charge.
- Second letter, lowercase: the secondary tone.
Two exceptions you will see in the chart: the eight NW shades (Natural Warm) carry both letters uppercase, and 5Ago and 9Ago use three.
That lowercase is not a typographic whim, and it is what was wrong in our chart until September 21: we wrote 4RR, 6RR, 5CR and 7CR with both letters alike, while Redken prints 4Rr, 6Rr, 5Cr and 7Cr. Leveling them loses which of the two tones dominates.
The families: N natural, A ash, B mahogany, C copper, G gold, I iridescent, M mocha, R red, V violet. B is mahogany, not brown, and this was wrong too: the numeric equivalent published by the retailer confirms it, where 5Br is 5.56 and 4Bc is 4.54. With B read as brown, the converter matched those shades to the wrong family.
