Rainbow dither QR code generator
The same pixel-dither texture as the classic version, but the colours swirl around the centre of the code in a full rainbow, from red through green and blue to violet. It feels like a glitchy gradient on an old monitor: busy, bright and unmistakably eye-catching.

Printing tip
Pale yellows and light greens scan poorly, so print on a clean white background and always scan a proof before running a batch.
Static code: it never expires, but the link can't change after printing. Need edits or scan counts? Make a dynamic code.
Questions
Do rainbow colours still scan?+
Yes. The design keeps every dot dark enough against the light background, uses the highest error correction level and is tested with real QR code readers.
Can I use it on a poster?+
Yes. Download the SVG for large formats, and keep the white border around the code.
Does the code ever expire?+
No. It is static, so it never expires, though the link cannot be changed once printed.

The next step
Make the code the artwork.
These tools make and check classic codes. AriaQR turns your photo, logo or illustration into the code itself, verified on real decoders before you download, with a link you can edit and track.
