Simply drag the .MOV file from the package folder directly into Davinci Resolve, either into the timeline in the 'Edit' or 'Cut' tabs, or to the project bin first.
To customize the color in Davinci Resolve, navigate to the Color tab at the bottom. Make sure to select the correct file before changing the color! Unless you have more .mov files in your edit, the outro will be labeled as 'Apple ProRes 4444', and the preview will be highlighted with an orange border.
Use the color picker tool to select the color that you want to change.
In the 'Qualifier' section of the bottom panel, turn off the Saturation and Luminance toggles. After that, you can change the 'Hue' slider at the bottom from 50 to any other value.
You can now experiment with the Hue slider to achieve the look you want!
