Colored numbers on CV controllers?

[SlowCoder]

While perusing eBay, I've seen a couple of auctions with what seem to be nonstandard controllers. Well, the controllers appear standard, but the keypad is colored.

 

Here's an example: eBay Auction -- Item Number: 150503799485

 

What is the deal with these?

I think that there is an overlay left in the controller. Maybe the overlay of the game Mouse Trap.

Yep, that's what it looks like! Thank you.
