Bill and I are aiming our efforts primarily at children as we refine and develop programs for them, but we believe that anyone can benefit from or enjoy exposure to trAction Painting. The adults in the upcoming event will be able to express themselves on a 5 x 10-foot canvas. I haven't yet selected the palette, but we won't start on a blank white sheet. Unless I'm going for a certain effect, I've largely abandoned white gesso as the substrate. For example, at the summer camp we just completed and the elementary school event before that, we tinted the gesso yellow. At the camp, we wanted primary colors as a base for a round of pastels on top of geometric figures. It was necessary to lay down only red and blue to get the tricolor base.
The primary?so to speak?reason for using tinted gesso is that some trAction paintings let the base show through. If I want to accentuate bike wheel patterns, for example, I don't want every square inch of canvas covered with tracks that eventually become less differentiated. At the same time, I generally don't want white to be the contrasting color element. It's boring.
The base was a kind of brick red in the deck painting Roz mentioned. The attached photo shows what it looks like after 14 Razor layers of paint, two of which are the house and trim colors. I was planning to stage the adult painting event on the deck, but the boards are old and some of the gaps between are rather yawning. Concrete garage floor will be much more hospitable to trAction neophytes. I still haven't decided on the primer color for this event, which happens midmonth. I'll document the festivities and be back with a report later.
