You have to provide a path which serves as the identifier for the mark, 
for example from within TextMate you can press ⌃R on the following 

	"$TM_MATE" --set-mark "$TM_APP_PATH/Contents/Resources/TextMate.icns" 
--line 3

This shows the TextMate app icon in the gutter’s third line. You can 
clear it again using:

	"$TM_MATE" --clear-mark "$TM_APP_PATH/Contents/Resources/TextMate.icns" 
--line 3

However, now that I just tested the above I realize that gutter marks 
are rendered as monochrome so that they match any theme.

Though should anyone provide a proof-of-concept for this, I can help out 
adding support for setting color marks. Could base this simply on image 
naming conventions to avoid needing new API.

The “difficult” part is scanning the current CSS file and generating 
image squares for all lines with color specifications, once we have 
that, it should not be a problem hooking it up to TextMate.
