Anything is possible when people are involved!
My dealer has STIHL chain on 100' reels, that they spin to custom lengths, and pre-packaged (factory spun) loops for the more popular sizes. They also get custom spun loops from the regional distributor when someone wants a chain type that they do not normally stock.
The dealer has little drawers with parts for many brands of chains that they have sold over the years (which is nice for me!). They are supposed to use yellow STIHL tie straps of the correct size and type with pro STIHL chain, and green STIHL tie straps of the correct size and type with low-kickback STIHL chain.
That does not mean that some folks can't make mistakes, or try to cut corners. I have seen tie straps installed inside out. I have seen tie straps from different types of STIHL or Oregon chains installed in loops. I just got a chain with 4 cutters spun in backwards! The low vibration chains even have different Right and Left side tie straps. Some Oregon tie straps may fit some STIHL chains and vice versa, although, there are often differences in thickness, hole size and spacing, etc.
I don't encourage mixing brands, unless identical (e.g. an Oregon tie strap used on an identical Husqvarna chain made by Oregon). If the correct tie strap was used, then the lack of color is incidental, as it wears off quickly in use. If they put the wrong color on, and the customer relied on that information, then some lawyers might get interested.
