that would at least give you a start but i think colors tend to change as they dry so it may be not that accurate

if you intend to paint the hulls then some painters have hand held color scanners that read the colors directly from a surface and then provide a maxing ratio to make up that color

or on re-reading your post are you wanting them to color the liquid white gelcoat something else, like yellow

either way better speak to them about it
