I was looking for something that was easy to duplicate years down the road if needed, so a fleet color was a base-point. Included in this was a requirement that it had minimal components (4 vs many different tints for example). I finally rested on a Fiat color "Arancio Narciso" (519A). But it was a tad too red for me, so it reduced the red tint by about 17%, and then increased the yellow tint by the same number of grams lost by the red (so that the weight of a quart/gallon/whatever was the same total weight as the unchanged fleet color). This resulted in a seemingly simple 4 tint orange that was more yellow than original, yet still based on a fleet color if I needed more later. Obviously John's or Russell's color suggestions are even simpler (over the counter so-to-speak).
