Like deep Parma violets or blue lavender it is a wonderful 18th century colour used for colouring the inside of furniture- like the lining of a jacket - or for using with as the base with Paris Grey on top and distressed, like on this sample piece of timber, where we have Old Violet painted as the base coat to Paris Grey to provide colour and the anchor it down, with some Old White to lift it.
A simple French side table with a marble top has been painted in Old Violet with Country Grey on the top and on a band below, making what was a rather heavy uncharacterful piece rather charming
ADD OLD WHITE-to make 'Schinkel'
Add 2 parts of Old White to 1 part of Old Violet and you get a greyed taupe I have called after a great 18th century German architect called SCHINKEL
ADD MORE OLD WHITE - to make 'Colombe'
Add 8 parts of Old White to 1 part of Old Violet for a soft grey like the underbelly of a dove, so I called it in French, COLOMBE
