I'm not sure how it does (sorry was playing with picture sizes to try to shrink them hense my post moving below yours). Maybe it has to do with the port as of this morning, it wasn't even done an hour ago, and maybe because my iPhone was unlocked by Telus and I'm just moving that to Koodo so I just swapped the sim.
Also I took a couple pictures of my booklet/card to show the colours/barcode I was referencing.
EDIT: I know with Telus, they changed the booklets/cards with each version. Version one/two were white on both sides of the card, but version one had one flower on the booklet and version two had two flowers. Version 3 got rid of the flowers and they began colouring one side of the card, purple for regular sim, green for micro sim.
Is yours a regular sim? Maybe Koodo has the colours inverted similarly to how Telus uses two different colours on the two different sizes.
