Heavy Body viscosity can also be reduced successfully with water. Remember: the more water added to the acrylics, the greater the subsequent shrinking of the paint layer. Too much water will reduce the binding capability of acrylic paints and tends to flatten out their sheen. When thinning out Golden Acrylics be sure to check out their extensive line of mediums. GOLDEN Primary Cyan, Magenta and Yellow in the HB line should be of special interest to artists who want a totally pared down palette or who are in need of a tool for teaching about color mixing and blending. They have been formulated to be close in color strength, so that one hue will not predominate over the other colors. The mixture of these products will produce an incredibly rich and infinitely varied wheel of color.
