You’ll get an in between level of colour which is 7/73 and 1/2. The lowest number always gets the “1/2” for example 1/2/of 4/3 and half of 5/3= 4/3 and 1/2What do you get if you mix these two colours together?? Wella 8/73 and 7/73 . I don't always get the whole half and half colour mixing. Would that equal 6/73 and if it does why not just use 6/73 in the first place or am I missing a viral link!? X
