Defect detection in objects

Hello friends,

I'm working on a AR project which I'm planning to develop on Hololens eventually, and I'm trying to find if the order of colors in a connector does not follow the reference object. To give an example, let's say the correct order is Yellow black black and red:

https://i.stack.imgur.com/LK04V.png

and looking at this image with the wrong order, we should be able to tell the order of colors is wrong:

I'm open to use OpenCV or online learning algorithms, but I just wanted to know if anyone has an idea of a proper algorithm or approach to do so.

Thank you!
