Natural tones (N) are neutral in color, which means they contain a balance of warm and cool tones. They are best for covering gray hair.

PRO-TIP: N is best for covering gray hair and giving a natural-looking result. Since gray hairs have lost their natural pigment, they soak up dyes more readily. That means that brighter colors and reds won't always look natural. If you prefer warm or red tones, mixing with a Natural (N) tone will give your hair a more uniform result.

Golden (G) tones provide warmth by blending in subtle yellow hues.

Copper (C) tones are vibrant and rich and are more orange in color.

Red (R) tones have concentrated red hues in their formula.

Mahogany (M) tones have both purple and red added for a more red-violet hue.

Chocolate (GM) is a blend of sublte gold and mahogany hues for a rich chocolate tone.

Ash (A) shades add a cool tone to the hair and are ideal for counteracting ‘brassiness.’

PRO-TIP: Ash tones can neutralize unwanted warm hues and work best when mixed with an (N) Natural tone.

Warm (W) is a blend of golden, copper, and mahogany to create a radiant, intense brown tone
