I recently featured green in one of my experimental paintings on paper, and used green again to form a grid in this one. I began with a light permanent green, using a brush to create the grid.
I painted the inside rectangles of the grid in a titanium white, and used parchment for the rest. After these colors dried, I painted over them in a thinned down bright yellow mixture. The ones underpainted with white came out brighter, which is what I intended.
I finished painting the background in parchment, and then began adding more shades of green over it. The paint dries very fast on this satin-finish hot-pressed Arches watercolor paper, so it was easy to overpaint quickly after the under-painting.
The final step was to draw outlines in a veridian green. Now I'll let the whole thing dry thoroughly before continuing.
