Some of the sample colors,I photographed in various stages.From the mixing of the pigment with water,and the addition of lime putty,to the various drying stages.I then labeled the back of the panels with the name of the pigment used.By premixing colors with water,adding the lime and storing them in glass jars under a layer of water-I am able to see the color of the paints while wet,and after reacting with lime.This way I have a more true idea of how they will actually appear when I use them to make images.By making the test panels of various colors I can then compare the dry color on the board,to the wet color in the jar.This should give me more control over the value range in the finished paintings.Shown here are panels of indian red and yellow ochre pigment,on wet lime putty,before drying.
