Simply drag the .MOV file from the package folder directly into Final Cut, either into the timeline or the project bin first.
In the timeline, select the outro file. Then, click on the Color Inspector icon in the top right corner. Select '+Hue/Saturation Curves' in the 'Correctors' dropdown.
You should see a 'Hue vs Hue' slider. You can adjust this slider to achieve the color you are looking for!
