Below are all color mixtures. I love the subtlety of the complex color hues.

 

 

The above image I tried out using the Winsor Newton granulation medium, also an epsom salt solution and then the next row is a table salt solution . Both the epsom salt saturated solution and table salt saturated solution precipitated salt crystals on the surface of the paper. probably not functional?

 

 

The above colors all are straight from the tube and have a have a sprinkle of kosher salt. Amazing the different ways the colors all responded differently to the salt.

The below - top 5 colors all have been mixed with Lunar Blue.  Top row has water and alcohol splatters, next row is Kosher Salt, next row is Table Salt, and the bottom row is drops of alcohol.
