There's an economic factor with paint as well, as I guess there always is with art and artists tool. The new brands of paint and the colours available are indicative of a time of a more professional class of painters who pay for the paint. The old stuff was all stolen, racked, or if you had big balls, taxed off other writers. BITD, the only nice paint available was Buntalac which you could only get from art shops, and was by the time i was involved, under double lock and key. I can the lilacs and pinks in some of those pieces and think that must've been a can on Bunt.
