I love the Indigo made by Holbein! It has an intensity that makes it possible to use it alone in a study and achieve the lights and darks in a range of values. It has rich deep color that does not lose its punch when pushed to the limits of light and dark. This series has been interesting, and I will start with the Indigo next time since it makes a value piece to work from when adding color in the subsequent pieces (which of course is the right way to start!).
Also, while on the topic of series, I refer you to a twice weekly letter from Painter's Keys that came to my Inbox this week. It speaks to the merits of working in a series and the freedom a series imparts.
This is Day 20 of the 30 in 30 Challenge! Check out the Challenge here. You will see a wide variety of pieces done by hard working artists from the US as well as across the world. A worthwhile diversion today.
