Olive green, mustard yellow, and chocolate brown seemed to be popularized in design, and oh how things had to match, in the late 60s and 70s. The colors were the imprint and indicators of the "time." .

Baby blue, etc., were the tell-tale "markers" of other times, and William Sonoma, which I love, plays on those colors and connotations - or memories conjured that people associate with the familar.
