How to change background colour one note?

What issue do you have?

Hi,
Is there a way of changing the rendered background colour of just one note?
I have a nice dark theme, but if I have note with a transparent png with black lines in it I cant see it properly
Some sort of html to paste in?
I dont want to change my CSS to have all notes with a lighter background colour
Thanks

As usual, after searching for ages with no success, I posted here

Then almost immediately found something that worked

pasted at the start of or end of note:

body { background-color: grey; }

sorry, but may help someone in future

For the Standard Joplin Default theme with white text I found this fitted my personal teste / eyes:

body { background-color: #575757; }

But to be honest it was better IMHO to change to black text as well, then I used this:

body { color: #000000; }
body { background-color: #7A7A7A; }
