What does "croma"mean?
I watched a youtube violin video which has a comment that asks"Is the landscape real or croma?"
I know it means whether the musician is really at that place or she's just in a studio with that background on a screen.
But I looked up the dictionary and there is no English word as croma.
Is that a typo or a loanword from Italian?
And are there other brief ways to ask the same question?
Thank you in advance.
