Here is how the paint looked while still wet.
Each new band of color was poured into the middle of the painting to mimic the pattern of a “fortification” agate (one where the bands form concentric patterns like a fortress). The red iron oxide bands alternate with white, light gray, and and dark gray to mimic the real colors of a Lake Superior agate.
The colors in the pour look lighter when wet. They darken and intensify as the painting dries. Also, the paint moves as it dries, stretching the pattern a bit.
Here is the work, almost fully-dry.
(The inside dries last, so dry to the touch doesn’t mean fully-dry yet.)
See how much the color intensified! That is because the pour dries like Elmer’s paste dries: white when wet, but clear when dry, so all the colors that had looked pastel when wet were actually much more vibrant, yet translucent. This is why I wanted to paint agates: the poured acrylic can really capture some of their subtle shine as well as the nuance of pattern.
