Shades of Old Violet

I have been working on color studies of shades of Annie Sloan Chalk Paint. Shades are made by mixing varying amounts of black, or in this case Graphite, with any color.  This is one of the ideas I have been considering for an old dresser using shades of Old Violet.   When mixing Graphite to make shades it is important to remember that it is not a true black. Rather it is a dark charcoal, with strong blue undertones. Any shades will become slightly more blue in addition to becoming darker. Notice how green Arles and English Yellow become as increasing amounts of Graphite are added. It is not necessarily a negative, just something to keep in mind.
