Forgive me as I’m new to this. In the instructions for the F4F the paint color designation for some areas lists two colors in this format: For example, XF-3:2 + XF-5:1. Is this the ratio of these two colors in order to get a final color? TIA
Yup. That’s the ratio of colors that they want you to mix together, so it would be 2 parts Flat Yellow to 1 part Flat Green.
