Here are some start-to-finish progress shots of Number 424 and Number 425.  I started these March 31st, the day after the auction preview at NCMA.  I am still playing with the same colors as I used in 423 but I have added a lighter orange, moved the orange inside and I am using 2 blacks (one turquoise, one blue) each with gray variant.  The exteriors are white shades of the two minor colors, chrome oxide green and van dyke brown.  I had originally planned these as dark paintings but decided against that; it felt too heavy, too neon, too 80s.  The paintings are based on drawings that I posted here.
