I really like the sediment that some pigments leave behind. I like the way some pigments catch the light, and some clump together. I like the water spots they create, and the movement that occurs in a finished piece when these effects are layered together.
When I first started painting with watercolors I couldn't quite get the hues that I wanted from mixing. I did a lot of research on pigment and color and decided that I would let myself buy as many colors as I liked, but I would try to purchase only single pigment paints. Those early tubes were Maimeri Blu because they were on clearance at the local shop.
Daniel Smith makes paints from semi-precious stones. They create amazing textures and interesting mixes. Once I started experimenting with these, Daniel Smith quickly became my preferred brand. When I began to seek out paints specifically for the way they granulated, these were the most exciting.
I'm particular about how the colors are arranged in my palette. The top holds rainbow pigments in rainbow order, the bottom right holds neutrals,- many of them are unique pigments from Daniel smith such as hematite and blue appetite. The I also arrange in rainbow order.
The bottom left and and two ceramic palettes are my working palettes. I have selected a limited palette for this section based on my favorites from the other two sections. I pull from the them as necessary while working but try to stick to my main palette to get to know my preferred pigments better and bring a sense of cohesion to my work. Since adopting this method I've found I am more pleased with the resulting work.
In the future I'd like to try mixing my own paints but I'll probably wait until I have a larger workspace to tackle that. Anna Valdez, @missannavaldez, mixed her own paints and the vibrancy of her oil paintings really stands out to me.
