Gradient Sunset renders the QR modules in a diagonal blend from warm coral (#FF5E62) to amber (#FFB347) over a soft warm-white background (#FFF9F5). It is the template for golden-hour marketing: travel campaigns, resort promos, festival announcements, and any brand whose photography lives at sunset. The gradient is applied as a single diagonal sweep across the whole symbol, which matters technically: a smooth global gradient keeps neighboring modules at similar luminance, while per-module rainbow gradients create local contrast chaos that scanners hate.
The honest engineering note: gradients cost contrast at the light end. The coral start of the gradient holds contrast around 4:1 against the background — workable for modern phones in good light, but the amber end is lighter, and any module region drifting too close to the background tone becomes a binarization risk. This template is therefore positioned as a large-format, good-light design: 30mm minimum in print, screen-first for social campaigns, short payloads to keep modules big. A dense, high-version gradient code is the exact combination that fails — small modules plus marginal contrast is multiplicative risk, not additive.
The finder eyes use the gradient too, but the inner eye dot stays solid coral: the three locators must remain the highest-contrast, most recognizable shapes in the symbol, because detection starts there. If detection fails, nothing else matters. The rounded label frame carries the CTA in solid coral text on the warm-white field — text is never gradient-filled, because thin gradient text fails accessibility and legibility simultaneously.
Scanability notes: proof the gradient on the actual output. Screen gradients and print gradients differ — inkjet banding can create visible steps in the blend, and each step edge is a potential false module boundary. Use high-quality print settings and test-scan the proof, not the screen mockup. On social, export at high resolution; platform recompression (especially stories and reels) blurs gradients, so keep the source large and the payload short. Never place this over a photo — the gradient needs its clean #FFF9F5 field. Keep an accessible high-contrast alternative ready for contexts where the gradient cannot go — inclusivity is part of good campaign design.
Best for: travel and resort promotional campaigns; hospitality seasonal offers; music and food festival announcements; lifestyle brand social campaigns; sunset-themed event invitations.
Avoid for: small print under 30mm; dense payloads (long URLs); placement over photography; low-light scanning contexts; industrial or clinical use; and any audience on older devices — the gradient's light end needs a decent camera.
Best for: - Travel and resort promotional campaigns - Hospitality seasonal offers - Music and food festival announcements - Lifestyle brand social campaigns - Sunset-themed event invitations
Avoid for: - Print under 30mm - Dense payloads (long URLs force tiny modules) - Placement over photography - Low-light scanning contexts - Older devices with poor cameras
