Which red works
Deep red (#b91c1c) gives 6.5:1 against white. Phone cameras read it well when it's this dark.
Some barcode scanners in shops light the code with red light, which makes red ink look pale to them. Phone cameras don't have that problem, but if a till scanner may read your code, use black.
Replace the sample link
The code on load points to example.com so you can see the colour. Paste your own link before you download. Then scan the preview with your phone, ideally in the light where the code will be used.
