You are correct, that is the colour coding Peavey uses.  The red dots on the speaker baskets are the + terminal.  (that means one spkr in pic is wired wrong polarity)

It looks like the Blue and Yellow wires are reversed, as long as the wires are connected correct on the PCB.

Check the colour of the 2 wires that are closest to the headphone jack, directly behind the jack on the PCB.
They should be the positive wires, the 2 wires closer to the back of the amp are the negative wires.
Cheers

When you reverse that speaker that has wrong polarity, you should notice better bottom end/bass response.
