Use the Colors window in Final Cut Pro for Mac
You can use the macOS Colors window in Final Cut Pro, giving you access to the familiar color pickers such as the Spectrum palette or the Pencils palette.

The Colors window has four sections: the icons at the top select picker interfaces; the large color swatch shows the current color; the middle section shows the active picker; and the row of boxes can be used to save swatches.
