Hi, Keith...
I have been watching a number of watercolor tutorials on Skillshare made by Louise De Masi, and I have found them to be very helpful. Here is what she recommends... Find a small ceramic palette with sloping wells. Place a small dab of paint at the top of the well and let it dry for a little while (maybe an hour). Then find a fine spray mister and give the paint dab a squirt or two. The watery paint that results will gravitate to the bottom of the well, where you can dip your brush in it if that's what you need. If you need a more intense color, dab your brush lightly over the re-moistened paint dab. Then she recommends dabbing your brush lightly on a towel to reduce the amount of moisture on your brush, especially if you are painting wet-on-wet. Charles Reid would not have liked this approach, but it works very well for Louise, and for me.
Good luck!
