To create a Prussian blue hue, you add a little warm red to Phthalo blue (green shade) and mix. Treatment with an acid ferro-cyanide solution will result in the unmasking of ferric iron in the form of the hydroxide, Fe(OH) 3, by dilute hydrochloric acid.The ferric iron then reacts with a dilute potassium ferrocyanide solution to produce an insoluble blue . Add a bit more red and you create an indigo hue, so I find phthalo blue the most useful. Good ideas. This just doesn't seem as useful as the shift from the more violet .
