Design best practices (so your QR scans first try)
Contrast: Dark foreground on light background
Quiet zone: Leave padding around the code
Size: Handouts 3–4 cm; posters larger (test from viewing distance)
Testing: Try iPhone and Android before printing bulk
Logos: Keep small (around 15–20% of QR), avoid covering complex finder patterns
Color: Avoid low-contrast pastel on pastel; use your brand colors strategically
Brand feel and UI animations
Your QR tool uses elegant text styles and color animations for buttons (reds, pinks, peaches, purples, blues, greens, yellows, oranges). It feels modern, not distracting—keeping the generator clean while looking alive. The cursive title font gives a creative, friendly vibe.
