*NOTE: In English, there are two spellings of the word colour. In American English, the word is spelled color. I have used the American spelling in this post because many of these expressions are used mainly in American English. Everywhere else (Canada, United Kingdom, Australia, etc.), the word is spelled colour.
An English learner recently asked me on Facebook to define some expressions in English that include color names! For each phrase, I have included a headline from an online newspaper that includes the phrase so you can see how it’s used in context. Here are 10 phrases and idioms in English that use color names!
a black eye – (1) an eye injury; the bruise (dark area on skin) that results when someone is punched/hit in the eye; (2) idiom – dishonour or shame
to blackball (someone) (verb) – to prevent someone from joining a group by voting against him/her, or to prevent a project from being approved by voting against it
to blackmail (verb) / blackmail (noun) – a crime; to threaten to tell someone’s secrets or harm them in some way unless that person gives you money or does what you want them to do
a brownout – a period of time in which electricity going to a house or building is reduced, because the power company cannot produce enough electricity to meet demand
a blackout – (1) a period of time when there is no electricity and therefore no lights or power; more severe than a brownout
a blackout – (2) a period of time when information is deliberately kept from the public (for example, a media blackout)
a green thumb – If someone is good at gardening and is able to make plants grow, that person has a green thumb!
a pink slip (idiom) – an announcement or notice from an employer that an employee is being laid off (the employee’s job is ending, the employee is not needed anymore)

red ink – A situation where an organization, business, or government is losing money (by spending more money than it is taking in) and accumulating debt; in the past, when a company was in debt it was written in red ink in the accounting books
a white elephant (idiom) – something (a possession, business venture, a building, etc.) that is useless and not very valuable, but that requires a lot of care and money, much more care and money than the thing is worth
