Sketched the tulips on a half sheet of 140# Fabriano Aristico Soft Press paper this morning. I had to use Photoshop Elements Contrast on it so the lines would show. Then did several swatches of colors to decide the palette and decided on Quin. Coral, Cadimum Red Light, Permanent Rose, Azo Yellow, New Gamboge, Viridian, Rare Green Earth, Fr. Ultramarine Blue, Pthalo Blue, Smalt (grayish-blue), and Quin. Violet. All of these colors have been used in the beginning portion of the painting as shown in the photo above. The photo was taken under a combination of fluorescent, incandescent and natural light then used Photoshop Elements Levels to lighten it so it to looked more like the painting.
