Could be brighter in color- but will continue to order from the Mule

I have ordered numerous times from Sticker Mule and have been very happy with the product - but the color isn't as bright in this round as it is in the image I produced. Also, the art review process was a bit confusing/stressful due to the back and forth about the QR code and it resulted in me changing the QR code altogether during the process and now it is the wrong code and I've had to re-order another set of 200 magnets, which won't be here on time, and the first order is of no use to me. So I've wasted almost $200 because of that.
