Setting the cursor color causes the character under the cursor to be drawn with the normal foreground color. When the cursor color is the same as the foreground color, you end up unable to see the character under the cursor. VTE has a special case that draws the character under the cursor with the background color when the cursor color is set to NULL.
Here's a patch which makes roxterm set the cursor color to NULL when it matches the foreground text color:

Subject: [PATCH] When cursor colour matches fg colour, set cursor to NULL
VTE has magic semantics for a NULL cursor colour, causing it to flip
the text colour for characters under the cursor so you can read them
that way.
