Xmas lights with white cords

Apparently, at Canadian Tire, and online, if I want multicolour Xmas lights (ideally LEDs), that I have to have a green cord. Only white cords are with white LEDs.

I considered buying one of each and moving the “bulbs”, but many of the systems are not socketed.

I want Xmas lights I can put up on the house, staple in, and LEAVE there.
