I can't think straight today! My client wants 7.23 but I don't have that in. I have the intensive series and base 7... What quantities do I mix? Eg 50 ml of base 7 to 25ml 0.2 and 25 ml of 0.3?
As a general rule of thumb where a shade has 2 tonal numbers the first accounts for 70% of tone and the second 30%
