[Ambiant-MATE-Dark theme] Can't see sursor when renaming files

It's a really minor issue, but I gotta deal with it.

When I go to rename I file, the text remains black, but the background is replaced with a white field while the cursor remains a very light green that I struggle to see. Sometimes I have to delete or insert a character in order to suss out where the cursor is.

If I can just change the cursor to black, I think that would be ideal.

In this screenshot, the cursor is between the 'e' and 'r'.
