I haven't seen state of play, but mixing colors/color theory can be quite fun!
Inks can be fiddly, but they can produce great results. They're more prone to tearing or reactivating and wearing away than normal acrylics so you have to be gentle with them after applying.
Also, you can glaze with most any acrylic paints in addition to inks. Some colors have more transparent pigments in them and will work better than others but the technique can still be used.
Thanks! I'm happy with how it turned out.
