This is not easy! :-) I'm getting a bit of feeling for the gradation but clearly need a lot of practice!
I figured enough blue for now and pulled the tape, sponged in ochres for fallen leaves, and spread a gradated wash. The wash pigment is a brand new acquisition. The Kremer order arrived today with lots of cool stuff. More on all that later but the pigment in question is Jarosite, a lemon yellow ochre from Cyprus. It builds up a lovely glow of great transparency. It's very manageable with gradation. An instant favorite! :-)
Quoting from the Kremer catalog:
"Lemon Yellow Ochre is the clearest yellow ochre occurring naturally, without the deeper tone of French ochres. Because of the political situation of Cyprus the mining of this rare and beautiful earth has been neglected, but now a small amount of manual production is once again available. Other deposits of natural ochre of this clarity may exist, but the Cyprian Limonite has always been famous for its unique hue."
By the way, very reasonable at $15US for 100 grams.
