Hidden Mickey Mystery Pin Packs - Red, Yellow, Purple, etc

[LetsGoToo]

Does anyone know if these different color pin packs always contain Hidden Mickeys from the same year?

For instance, does the yellow pack always include pins from 2013, or are they all random years?

Just an update to my own post:

I bought a few purple packs and the pins were all Hidden Mickeys from 2013. I'm not sure if ALL purple packs are sold that way or not. Just FYI.
