[racket] how can I change image's tint?

Greetings,

I am not sure, but couldn't you just convert the image to black&white and
then just overlay a colored rectangle with a low opacity (over it).

Or you could try to place a colored rectangle over the colored image instead
of turning it to black and white, to make things easier.

I am not sure if this will do the trick, but this way, its pretty easy to
do.

Sincerely,

Mathew K.
