When I originally did the first (green) mask back in 2012 I wanted to do a series using a very simple pallet of primary and secondry colours. It's taken me more than 2 years but I've finally got onto the second one. Maybe in 2 more years I'll get onto the 3rd.
Here are the inks for starters.
(The design sketch for this mask can be found in the previous post)
And the first peice.
