You can color any type of color on your QR code the way you want it to be.
However, there are certain rules you need to follow in making your QR code colors correct to make them readable and scannable, so it is important to remember :
- Never to invert your QR Code colors. The pattern color should always be darker than the background color. QR Code readers are set to scan QR Codes with a darker contrast to the background.
- The contrast of your QR Code colors should be observed
- avoid blurry QR Codes
- don’t get your QR code pixelated
- adjust the size of your QR code depending on the advertising environment
