Cursor colour change on certain themes

[Mark Davies]

Is your feature request related to a problem? Please describe.
On certain themes it is really difficult to see the cursor, i.e. the Jynx theme, it is super difficult to locate my mouse cursor in a reasonable amount of time, I feel as though the cursor colour should change per theme so that I can locate my mouse cursor/

Describe the solution you'd like
Good colour disparity between theme and mouse cursor

Additional context
Would print screen but cursor doesn't appear - sad times
