Splash the prussian blue through clear H2O A tiny touch of fresh lemon and wait for it to go absolutely spectacular, mad as a hatter, wow. The pigment disperses for all it is worth The results are amazing like nothing on earth. On a wet piece of watercolour paper taped down drop from a wet paintbrush a touch of deep brown Then add a nice bright shade of transparent ink Anything from a scarlet to a permanent pink. The scattering of colour is an explosion of rainbows Browns, ochres and rouge combine into **** glows. Drop any shade onto damp paper and another and you will hav your mind blown away to some other colour dimension. It is addictive, best you have seen Complimentary colours like the red and the green. Try it and you will say wow.
