How to set the color of the cursor in Geany?

I'm using Geany on Windows and would like to set the cursor colour to something more conspicuous.  In my AppData\Roaming\geany\filedefs\filetypes.common, I have set caret=caret;;true cursor_color=yellow While the caret-setting (changing the default to a block cursor) works (which obviously indicates that I configured the setting in the correct file), the cursor_color setting does not seem to have any effect, as the cursor is still a light grey. What did I do wrong?  How can I set the color of the cursor in Geany?
