QR code should ideally be inverted #3

It is white on green. Since QR codes are typically black on white, this means some QR code scanners can't read it. Many do, so not critical. If white background causes a problem with not having enough border or runs into the text, don't change.

Per http://blog.qrstuff.com/2015/09/09/colour-qr-codes

While a reverse image QR code is supported under the ISO standard, it’s quite surprising how many scanning apps can’t read a reverse image QR code. Unfortunately this a scanning app thing and not a QR code thing so if you are intending to publish a reverse image QR code it might be a good idea to do a test scan on it first
