Q1. What is "invisible earnings"? I can't find out the meaning or example sentence in my dictionary. Is it some 'profits related to mind or spirit'?

Q2. My dictionary says "invisible green" is "very dark green". How can it be so? Doesn't 'invisible' mean 'transparent'? So 'Transparent green' is 'light green, isn't it? Would you explain why not?

1 Answer 1


The Cambridge Dictionary offers this definition of invisible:

used to refer to money that is added to a country's economy by activities such as the service and financial industries rather than the production of goods in factories

Invisible green is not invisible. It is a colour that can be used to digitally render an alternative image into the part of a picture or video that is this shade of green. I don't know whether they still do it that way, but weather presenters used to stand in front of a green screen, then the weather map was digitally added to the area that was green.

  • Your answer to Q1 couldn't be clearer. But Q2 answer is a little bit hard for me to understand. Anyway, thank you for your time and answer:)

  • @mystery put in simple terms, "invisible green" is not a real colour, and it's not invisible. It's a special term used to describe an image processing technique. Have a look at the link for more information.
