Many people have wonder why some colors have more brilliance than others or why some are more beautiful and brighter. The key is in the understanding of formulation a color for example using red orange base to a golden brown will create a much brighter brown gold it’s the same idea if I had gold co concentrate to my formulation. 60 grams on 5n with 10 grams of gold concentrate will look shiny and with more brightness than not adding gold to my formulation.
