Lavender (color)
By 1930, the book A Dictionary of Color identified three major tones of lavender--[floral] lavender, lavender gray, and lavender blue, and in addition a fourth tone of lavender called old lavender (a dark lavender gray) (all four of these shades of lavender are shown below).  By 1955, the ISCC-NBS Dictionary of Color Names listed dozens of different shades of lavender.
