did you try setting the cursor-type variable?
,----
| cursor-type is a variable defined in `C source code'.
| Its value is t
|
|   Automatically becomes buffer-local when set in any fashion.
|
| Documentation:
| Cursor to use when this buffer is in the selected window.
| Values are interpreted as follows:
|
|   t             use the cursor specified for the frame
|   nil           don't display a cursor
|   box           display a filled box cursor
|   hollow        display a hollow box cursor
|   bar           display a vertical bar cursor with default width
|   (bar . WIDTH)         display a vertical bar cursor with width WIDTH
|   hbar                  display a horizontal bar cursor with default height
|   (hbar . HEIGHT) display a horizontal bar cursor with height HEIGHT
|   ANYTHING ELSE         display a hollow box cursor
|
| When the buffer is displayed in a non-selected window, the
| cursor's appearance is instead controlled by the variable
| `cursor-in-non-selected-windows'.

as for colour, i have this in my .emacs:
,----
| (setq default-frame-alist
|       '((foreground-color . "black")
|         (cursor-color     . "Coral")
|         ; .... other settings
|         ))
