Hello,
I would like to accomplish the following:
Remove all red tones from an image the looks like this:
https://upload.wikimedia.org/wikipedia/ ... 08.svg.png

And if necessary make the black and grey tones darker afterwards.

It would be great, if anyine could give me a hint, how to do that?

Thank you.

Alexandra

Hello,

Try some color filtering.
