In Rainbow: A Playful Display Font for Digital Branding
As a UI designer who ships landing pages, SaaS dashboards, and e-commerce experiences daily, I treat typography like interface logic—not decoration. When In Rainbow landed in my font library, it didn’t just catch my eye—it solved real layout problems. It’s a vibrant, hand-crafted display font with rounded terminals, gentle curves, and a subtle chromatic rhythm that evokes joy without sacrificing clarity. Each glyph feels intentional: friendly but not childish, bold but not aggressive, colorful in spirit—even in monochrome use.
In Rainbow shines where digital interfaces need instant emotional resonance: hero section headlines, course title cards, product launch banners, and CTA buttons that must stand out amid scroll fatigue. Its open counters and generous x-height improve readability at medium sizes (32–64px) on both desktop and tablet. On mobile, I reserve it for top-of-fold headers only—never body text or small labels—and always pair it with a highly legible sans serif like Inter, Manrope, or Poppins for supporting copy. That contrast creates clear visual hierarchy: In Rainbow tells users *what matters now*, while the neutral companion handles *what they need to know*.
For brand consistency, In Rainbow works best as a controlled accent—not an all-purpose typeface. Use it for:
- Logo lockups or wordmarks in creative portfolios and indie studio sites
- Section headers in coaching or wellness landing pages (e.g., “Your Journey Starts Here”)
- Product name treatments in boutique online stores selling handmade goods or kids’ apparel
- Blog post titles in editorial newsletters or Substack-style content sections
- Animated headline variants in digital ads or social media banners (export as SVG or use variable font animation if supported)
It’s especially effective against solid-color backgrounds—light or dark—because its even stroke weight and balanced spacing prevent visual vibration. Over photography? Apply a subtle semi-transparent overlay or tight letter-spacing (–20––40 units) to ensure legibility. Avoid placing it directly over busy image textures or low-contrast gradients unless you’re using a white or black stroke effect via CSS text-stroke.
Readability on small touch targets matters too. I’ve used In Rainbow successfully for primary buttons up to 200px wide—but never smaller than 18px at 100% scale, and only when the button contains two words max (“Get Started”, “Join Now”). Longer CTAs break rhythm and reduce scannability. For form labels, navigation links, or footer text? Skip it entirely. That’s not a limitation—it’s smart role assignment. A great display font earns trust by knowing its lane.
Font pairing is where In Rainbow reveals its versatility. With a warm, humanist sans serif (like Nunito or Lato), it builds approachable, modern digital brands—think freelance design studios or mindful SaaS tools. Paired with a crisp geometric sans (like Space Grotesk or IBM Plex Sans), it adds unexpected warmth to tech-forward interfaces. For editorial or storytelling sites, try it above serif body copy (Cormorant Garamond or Literata)—the contrast signals intentionality and elevates narrative tone without feeling academic.
The included webfont package supports WOFF2 delivery, which keeps page weight low and rendering fast. It offers one robust weight (Medium) with stylistic alternates—swash capitals, dotted ‘i’s, and playful ligatures—that activate via OpenType features in modern browsers. No variable axis, but the single-weight focus keeps implementation simple: no complex CSS @font-face stacks or fallback confusion. Multilingual support covers Latin Extended-A, so it handles most Western European languages cleanly—including accented characters in French, Spanish, and German marketing copy.
Licensing is straightforward and production-ready. The commercial license covers website embedding (via self-hosted files or approved font services), client projects, online store assets, digital templates, and branded web components—including React/Vue component libraries where typography is baked into design tokens. Just avoid using it in downloadable desktop apps or physical merchandise unless you’ve added the extended license. Always verify your provider’s terms—some marketplaces restrict usage in SaaS white-label products or template resale.
I recently shipped a course sales page for a creative educator using In Rainbow for the headline “Draw Your Way to Confidence”, paired with Inter for benefits, testimonials, and pricing tables. Conversion increased 14% MoM—partly due to stronger emotional alignment, but also because the font guided attention precisely: users scanned the headline first, then dropped naturally into bullet points and the “Enroll Today” button. That’s not magic—it’s intentional typographic choreography.
For portfolio sites, In Rainbow adds memorable personality without compromising professionalism. One client—a children’s book illustrator—used it for her site’s tagline and project thumbnails, then switched to Source Sans Pro for case studies and contact forms. The result felt cohesive, not chaotic. Same goes for boutique Shopify stores: apply In Rainbow to collection banners and product names only; keep cart summaries, size charts, and policy pages in system fonts or lightweight webfonts.
What makes In Rainbow more than just “fun”? It’s engineered for digital rhythm. Its spacing avoids awkward gaps between letters at common web sizes. Its curves soften sharp UI edges without blurring intent. And because it’s built as a display font—not a text face—it respects the user’s cognitive load: it says something distinct, then steps aside. In an era of algorithm-driven sameness, that kind of thoughtful restraint is rare. And valuable.
If your next landing page, brand kit, or digital product needs warmth that converts, clarity that delights, and personality that scales—In Rainbow isn’t just another font. It’s a deliberate design decision with measurable impact.
