hello, to your question: i dont remember the exactly proportion for the blond hair, because i'm working to the feling, but i use a base of napel yelow, with a touch of aurora yelow, first step ligth is napel yelow with titanium and second ligth titanium. brun umber and burn umbur with black for the shading.
for the blue ???? i think base windsor blue, "turquoise"; and indigo; ligth more turquoise in base ad napel yelow. 1 st shading more indigo in base; 2 nd ad bleu black.
for the next i' take note of my mixing to give you with more precition.
tank for your coment.
