NEUTRAL- preblended meaning equal parts of neutral which also is equal parts cool /warm pigment Natural real pigment count would be warm having more warm red/yellow- pheomelanins and less blues- eumelanin pigments 2/3ths warm 1/3rd cool and the Color Sync Neutral is 1/2warm and 1/2 cool and is considered cool, since cool always dominates.
ASH- preblended; would have neutral and blue/grey in various degrees, the darker levels have different levels of the Blue/ Grey the ratio, at a level 4/5 you have more blue than grey and more of that tone than neutral to counter the underlying pigment at that level which is red/red orange. As you go up the levels, the blue/grey turns to grey, then to violet to soft violet in the higher level 8/9/10. Again in different ratios to compensate for the ULP.
GOLD- has a brown Base with the neutral warm/cool balance brown in the lower level up to pure gold at the lighter levels.
WARM NEUTRAL- has a brown Base with red & gold undertones, can be used to fill & Color at the same time- it is the perfect caramel Color.
COPPER GOLD- less Neutral Base -neutral and more red brown/blonde; red/brown/gold/copper pigments in various degress with strong copper/gold in the lower levels and light red copper blonde.
RED BROWN/BLONDE- less Neutral Base; gives a red brown in the lower levels with less neutral and red blonde in the lighter levels indifferent ratios.
RED COPPER- VERY little Neutral Base; very vibrant red copper at the lower levels and lighter levels it is more copper red.
RED VIOLET- VERY little Neutral Base; vibrant eggplant at the lower levels to pure violet blue pigment at the ligher levels.
