A Surprisingly nice yellow

It's been rainy all weekend, so I decided to do some research into various color palettes. Handprint.com is a marvelous website for watercolor information. I found it very interesting that the author, Bruce MacEvoy likes PY150, which is a nickel Azo. Winsor & Newton label it as Transparent Yellow, series 1A. Be advised that they also have a Transparent Yellow, PY97 (Arylamide) which is a series 2. That means it's a bit more expensive, about $4. The colors on first glance aren't even similar, the series 1A yellow looks like yellow ochre in the tube, while the series 2 yellow is clear and bright. I consider myself a power-user of transparent yellow, and had considered the series 1A a mistake until yesterday. This yellow is rich, and when blended out with water it becomes bright and transparent. It lifts out almost to the white of the paper and makes a wonderful orange when mixed with Cadmium Red PR108. Here's a little sparrow I painted using PY150. watercolor on 100% cotton paper
