If I use the sequence Command-Shift-4 Spacebar to capture a menu selection, the resulting images are monochrome. I'm on Yosemite and the result is the same on two devices. Any idea what's going on? All other screen captures are in color. Skitch app Menu Snapshot option gives the same result.
BTW I've used to use the Comm-sh-4 crosshair capture but just at the very moment you lift the cursor to complete the drag, something causes the cursor to select the next menu item, so you capture the menu item without it being highlighted.
