green with envy
. Some people are green with envy because a friend has more dollars or
greenbacks
. Dollars are called greenbacks because that is the color of the back side of the paper money.
The color black is used often in expressions. People describe a day in which everything goes wrong as a
black day
. The date of a major tragedy is remembered as a black day. A
blacklist
is illegal now. But at one time, some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations.
In some cases, colors describe a situation. A
brown out
is an expression for a reduction in electric power. Brown outs happen when there is too much demand for electricity. The electric system is unable to offer all the power needed in an area.
Black outs
were common during World War Two. Officials would order all lights in a city turned off to make it difficult for enemy planes to find a target in the dark of night.
