MattEverst, I did (years ago) just like you seem to be indicating you are planning to do now; I wanted to paint a new implement to match my tractor, so I took small, removable parts (one orange, the other gray) to the paint store. They have books with every conceivable shade of orange, and gray. I compared my part(s) with the paint 'chips', and when I found (what I thought was) the best match, they took the "numbers" and mixed up a quart each.
I do not remember the name of the colors, but unless you choose the same brand as me (Sherwin Williams), it wouldn't help; besides, you might well think some other shade was closer. I do remember it being a painless way to match colors, and didn't add any cost, or time - maybe I do not have as 'discerning' an eye as you, I just don't think it is all that critical for an implement.
If it had been more critical for me, the store offered to 'match' the paint; whereas they would have one of their 'experts' match the shade exactly. I would have to leave the part(s) overnight, and there would be a $35 charge (per color). My choice was easy! It's a tractor, not a show car! If it was that critical, I really don't think I would trust someone else's "numbers" to transfer to a different 'brand', or even a different store of the same brand- or even the same store, years later.
I don't understand Kioti's reluctance in 'publishing' their color formulas. Last I checked even the Kioti dealers couldn't get official Kioti orange or gray.
