Color Palette Generator

Color Palette Generator - Create Beautiful Color Schemes

A powerful color palette generator with two modes: manual creation with color harmony rules (monochromatic, analogous, complementary, triadic, tetradic) and automatic extraction from images using advanced color quantization. Features include 12 preset palettes, multiple export formats (CSS, SCSS, JSON, Array), and the ability to download palettes as images. Perfect for designers, developers, and anyone working with colors. See also our Gradient Generator and Color Mixer.

How do I generate a color palette quickly for a new project?

Start with the color you already trust — usually a brand primary, a hero image accent, or a feeling you want to evoke. Paste its HEX into the base color picker, then click a harmony button: Analogous gives you a calm, low-conflict scheme (good for content sites); Complementary gives a high-energy two-color contrast (good for CTAs); Triadic distributes three balanced accents (good for editorial layouts). If you have no starting color, drop an inspiration image into From Image mode and let k-means clustering pull five dominant colors. Refine each swatch by hand, then export. A solid first-draft palette takes under two minutes this way, and you can always layer Shades and Tints on top to expand it into a full design-system ramp.

What is the difference between monochromatic, analogous, complementary, triadic, and tetradic harmonies?

These are five classic positions on the HSL color wheel. Monochromatic keeps a single hue and varies only lightness and saturation — calmest, hardest to misuse. Analogous picks neighbours within roughly 30 degrees (blue, blue-green, green) — natural and cohesive. Complementary picks the hue exactly 180 degrees opposite (blue plus orange) — maximum visual tension, ideal for one accent against one background. Triadic picks three hues 120 degrees apart (red, yellow, blue) — balanced but lively, common in playful brands. Tetradic picks two complementary pairs forming a rectangle on the wheel — richest and hardest to control; usually one colour dominates while the other three play supporting roles. Pick the rule that matches the emotional volume of the page.

How does extracting colors from an image actually work?

When you upload an image, the tool downsamples it to a manageable pixel count, then runs k-means clustering in RGB space. Each pixel is treated as a 3D point; the algorithm picks k random centroids (k equals your chosen color count), assigns every pixel to its nearest centroid, recomputes each centroid as the mean of its assigned pixels, and repeats until the centroids stop moving. The output is k colors that minimise total distance to all pixels — effectively the most representative tones in the photo. This handles JPEG, PNG, WebP, BMP, and GIF up to 10MB locally; nothing is uploaded to a server. For brand work, try logos, product shots, and mood-board photos; the algorithm naturally pulls dominant colors rather than rare highlight pixels.

How do I export the palette into my Figma, Adobe XD, or code project?

Use the right format for each destination. For Figma and Adobe XD, copy the HEX list and paste swatches one by one, or export JSON and import via a token-sync plugin like Tokens Studio. For raw CSS, use the CSS Variables export — it produces :root { --color-1: #...; } which you reference as var(--color-1) throughout your stylesheets, giving you one-line theme overrides. For Sass/SCSS pipelines, SCSS Variables produce $color-1: #...; which compile away at build time. For JavaScript apps (React, Vue, Tailwind config), use Array or JSON format and feed it into your theme object. For client presentations, download the palette PNG. Always rename generic --color-1 to semantic names like --brand-primary or --surface-elevated before shipping.

How many colors should a design-system palette actually contain?

A working design system needs more than the five or six swatches a harmony generates. The common pattern is: one brand primary plus 9 tints/shades of it (50, 100, 200 ... 900 stops); one or two secondary brand colors with the same ramp; a neutral gray ramp of 9-12 stops for text, borders, and surfaces; plus five semantic colors (success green, warning yellow, danger red, info blue, plus a focus ring) each with their own light/dark pair. That is roughly 50-70 tokens. Use this generator to lock in the five base hues, then use the Shades and Tints buttons to expand each base into its full ramp. Material Design, Tailwind, and Radix all follow versions of this structure.

Is my palette WCAG accessible, and how do I read the built-in contrast audit?

A pretty palette is useless if users cannot read text on it, so this tool now ships a built-in WCAG Contrast Audit panel below the export options. For every swatch it computes the contrast ratio against white (#FFF) and black (#000) using the standard WCAG 2.1 relative-luminance formula, then tells you the best text color to place on that swatch. Read the badges like this: AAA means the ratio is 7:1 or higher; AA means at least 4.5:1, which passes body text; AA Large means 3:1 to 4.5:1, only safe for large text (18pt, or 14pt bold); a red Fail badge means under 3:1 and unusable for text. Mid-tone colors are the usual failures — a vibrant teal looks great but rarely passes against white, so the audit will steer you to black text instead. To fix a failing pair, darken the foreground or pair the brand color only with whichever of black/white the panel recommends.

How do I tune harmony output that looks too garish or too dull?

Raw color-wheel harmonies often produce cartoonishly saturated results because they keep the base saturation and lightness across all swatches. The fix is to convert each swatch to HSL and adjust independently. To calm a garish palette: drop saturation on supporting colors to 30-50% while keeping the brand color saturated; this is the dominant-with-mutes principle behind almost every premium brand palette. To wake up a dull one: push lightness contrast — set one swatch near 95% (a near-white surface) and one near 15% (a near-black text). The 60-30-10 rule is the proven default: 60% dominant neutral, 30% secondary, 10% accent. Use this tool to generate the math, then nudge HSL manually to taste.

Why do my image-extracted colors look duller than the original photo?

Two things are happening. First, k-means returns the mean of each cluster, and the mean of a saturated highlight plus a darker midtone is always a less saturated tone — averaging desaturates by definition. Second, photos rely heavily on micro-contrast and gradient transitions that you lose when you reduce thousands of pixels to five flat swatches. The fix: re-extract with a higher color count (10 instead of 5) and you will recover the brighter accents that were being averaged out. Then manually delete the muddy middle colors and keep only the saturated highlights and the darkest shadow. Alternatively, sample directly with the dropper tool on the most vivid pixel rather than relying on cluster averages — useful when you want a specific glow color, not an average.
