Recently I took an online course with Australian sketchbook artist and former architect, Liz Steel with her SketchingNow Watercolours course. She is an amazing artist and a very good instructor. I highly recommend her! I've taken several of her online courses and first came across her as an instructor in Sketchbook Skool, another source of great sketchbook courses online.

Liz led us through a variety of exercises with our watercolors to become more familiar with what our particular paints would do and things to consider when painting on location. One of the lessons was about mixing colors and the benefits of knowing certain combinations of color mixes before going on location so that when that kind of combination was needed it would be easy to mix rather than guessing. She suggested that we make a color mix chart of the paints in our palettes but it wasn't a requirement for the course since it does take a long time to do. However, I find making color charts a lot of fun and rather meditative, so here is my color mix chart of my current travel palette.

My paints are a combination of Daniel Smith (DS), Winsor & Newton (WN), Holbein, Schmincke and Sennelier.
