What is a color palette generator?

Colour palette generators are one of the most-searched designer-tooling categories on the web — somewhere in the multi-million queries per month for 'color palette generator' / 'color scheme' / 'coolors' / 'paletton' across the English-speaking internet, with heavy long-tail traffic for the specific harmony schemes ('triadic color palette', 'complementary colors', 'monochromatic palette generator'). The category is dominated by a handful of ad-supported hosted sites (coolors.co, paletton.com, color.adobe.com, colorhunt.co, mycolor.space, huemint.com) that all run the same underlying HSL hue-rotation maths and offer roughly the same 5-card output. None of them ship a memorable visual identity beyond the genre's default 'big grid of colour squares'; most of them upsell to a paid tier for the obvious export formats (Coolors gates several behind a free-account signup); all of them surround the working surface with sign-up CTAs, 'pro' modal banners, and related-trends modules heavier than the swatches themselves. The actual logic is small — HSL conversion is a 30-line function, the six harmony schemes are hue rotations around a wheel, the contrast calculation is the WCAG 2.1 luminance formula. Owning the page yourself means no ads, no account wall, no data collection, and a visual signature (Pantone-style swatch cards with EDITION numbers + monospace hex metadata on a designer's pinboard) that nobody else has shipped.

Real-world examples

Designer kicking off a new brand identity

Designer needs a palette for a SaaS landing page. Lands on the generator, types a primary brand hex into the base picker, switches the scheme chip to 'split-complementary', re-rolls 4-5 times until the support colours land. Locks the brand colour, re-rolls the rest twice more, accepts the result, hits Export → Tailwind config, and pastes it into their tailwind.config.js. Total time from blank page to shipped tokens: ~2 minutes.

Frontend dev needing accessible text colours

Engineer wants to pick the right ink colour for a card that uses one of the generated palette colours as its background. Reads the auto-coloured hex label on the swatch — that's the contrast-checked black/white choice already. Copies the hex of the swatch with one click, drops it into the card's CSS, then uses the same auto-pick logic for any other text-over-fill decisions in the design.

Sharing a colour direction with a client

Brand consultant is exploring directions with a client over Slack. Generates 3 different palettes (one analogous warm, one triadic primary, one monochromatic), clicks Share on each to grab a URL, pastes all three into the thread. The client opens the links on their phone and sees the exact same swatches the consultant saw — no PDF, no Figma file, no account.

Why FloopFloop fits color palette generator projects

The reason Coolors and friends exist is that wrapping HSL hue rotation in a webpage is a viable business model — ads, account upsell, and minimal effort, nothing else. The unique thing FloopFloop ships on top of that is the *aesthetic*: Pantone-style swatch cards with EDITION numbers, monospace hex / RGB / HSL metadata strips, a designer-red accent CTA that presses like a real button, JetBrains Mono on the numerics and Inter on the body, sitting on a warm cream pinboard that reads as a designer's studio rather than a configurator dashboard. Five colour variants (designer's pinboard cream, photographer's studio charcoal, print shop cool white, mid-century book sage, midnight noir) cover the obvious skin choices without making every palette generator on the internet look the same. The whole thing is client-side, so the visual IS the differentiator — exactly the dimension where AI-generated styling wins against every hosted competitor.

Build a Coolors-style palette generator. Five Pantone-style swatch cards across the page: each card is a top 70% colour fill with the hex code centered (auto-picked black or white via WCAG contrast so it's always legible) and a bottom 30% white 'tag strip' showing an EDITION number, the hex code, and RGB / HSL values in a monospace font. Spacebar re-rolls the palette; per-card lock pin keeps a colour you like while the rest re-roll. Six harmony schemes (analogous, complementary, triadic, split-complementary, monochromatic, tetradic) selectable from a row of chips at the top. Share button writes the palette to the URL hash and copies the share link. Export menu dumps CSS variables, a Tailwind theme.extend.colors block, or a JSON file. Visual: a designer's pinboard — warm cream desktop, cards sitting with a faint drop shadow, JetBrains Mono for the hex / RGB / HSL strings, Inter for body, a designer-red accent on the primary CTA.

Create a brand-colour explorer. Start with the user's primary brand hex, then generate a 5-step monochromatic ladder (light surface / surface / brand / brand-dark / ink). Also surface a complementary highlight + a split-complementary support pair as separate rows. Per-card 'use this colour' button copies the hex; an 'export' button dumps the whole set as a Tailwind theme.extend.colors block ready to paste into a tailwind.config.js.

Build a colour-contrast checker. Two big colour pickers at the top (foreground + background), a giant live preview panel below showing the foreground colour text on the background colour at 16px, 24px, and a heading size, plus the calculated WCAG 2.1 contrast ratio with AA / AAA pass-fail badges for body text + large text. A 'flip' button swaps the two colours. A 'suggest accessible alternative' button adjusts the lightness of the foreground in HSL until it crosses AA, showing the new hex.

Build a colour palette generator with five visual variants: designer's pinboard (warm cream + designer-red accent), photographer's studio (charcoal felt + amber accent), print shop (cool white + cyan-print blue), mid-century book (sage mat + sienna red), and midnight noir (near-black + crisp white cards). Same swatch-card cohort + monospace metadata across all of them — only the canvas backdrop + accent colour swap so the layout reads as one identifiable thing.

How is this different from Coolors, Paletton, or Adobe Color?

Hosted palette tools work — Coolors, Paletton, Adobe Color and Color Hunt all run the same HSL hue-rotation maths under the hood — but they're ad-supported, sign-walled (Coolors locks several export formats behind a free account), and surrounded by SaaS chrome (signup CTAs, 'pro' upsells, related-trends modules) that crowd out the swatches themselves. The version FloopFloop generates is yours: nothing leaves the browser, no account, and the visual (Pantone-style swatch cards on a designer's pinboard) is a register no other generator ships — most of them look like configurator dashboards.

What harmony schemes does it generate?

Six. Analogous (5 hues ±30° around the base for soft, related palettes), complementary (the base + its 180° opposite plus a darker neutral anchor), triadic (three evenly-spaced 120° primaries plus light/dark support), split-complementary (the base + the two hues ±30° around its complement — softer than full complementary), monochromatic (five lightness rungs of one hue, useful for brand-colour ladders), and tetradic (a rectangle on the wheel: base + 60° + complement + 240°). Schemes are computed via HSL hue rotation, which is what professional design tools use — RGB jitter produces 'random' but not 'harmonious' palettes.

How does the lock + reroll work?

Each swatch card has a lock pin in the top-right corner. Toggle it once and that card stays put through every re-roll; toggle it again to release. Press Spacebar (or click the big 'Roll palette' CTA) and every unlocked card refreshes with a new colour from the current scheme + a fresh random base hex. The selected scheme also re-applies to the unlocked cards when you change schemes, which means you can lock the two colours you've decided on and explore variations for the remaining three without losing your commitments.

Can I share or export a palette?

Two paths. Share writes the current scheme + 5 hex codes to the URL hash (e.g. #analogous/3B82F6-60A5FA-93C5FD-...) and copies the full URL to the clipboard — a recipient opens the link and sees the exact palette without any server round-trip or account. Export dumps the palette in your format of choice: CSS variables (drop into :root), a Tailwind theme.extend.colors block (paste into tailwind.config.js), or a JSON file with scheme metadata. All exports run in the browser as Blob downloads — no server, no data collection.

Is the contrast label on each card accurate?

Yes. The hex label inside each swatch fill is auto-coloured black or white based on the WCAG 2.1 relative-luminance formula (0.2126·R + 0.7152·G + 0.0722·B with the sRGB linearisation), comparing the contrast ratio against the fill for both black and white and picking the winner. That's the same calculation the WCAG accessibility tooling uses, so the label is always legible regardless of which colour the generator landed on.

Is my palette sent anywhere?

No. The colour maths, lock state, copy-to-clipboard, share-link generation, and export-file building all run via plain JS in the browser — there's no fetch to anywhere except /api/health (which doesn't see your colours). The page is force-static, so it's a CDN-cached HTML+JS bundle with no per-request server work. The share link encodes the palette in the URL hash, which by spec is never sent to the server.
