Yes, this is probably due to the fact that the original model is quite dated and not brought to FS22 properly hence the brighter green and some purple hinges. I would fix it, but I don't know when I'd get the time to, as I'm a lot busier now than I was this time last year. If you could send a screenshot where the purple hinges are on the model, that would help me pinpoint where the point of focus will be when I work on the mod next.
