Color Palette Generator

Give this color palette generator one base color and it hands back five ready-made schemes: complementary, analogous, triadic, split, and monochromatic, each on its own tab with copyable hex codes. It's a color scheme generator grounded in wheel geometry rather than random swatches, so the combinations follow the same rules art teachers have taught for a century. Reach for it as a palette maker online when a landing page needs an accent for its primary blue, or when a chart needs three hues that feel related but stay distinct. Type or pick the base, click through the tabs, and copy a single color or the whole set at once.

How to use

01

Set a base color

Pick with the swatch or type a hex value like #6366F1 into the text field. Every harmony recalculates from this single input the moment it changes.

02

Click through the harmony tabs

Complementary, Analogous, Triadic, Split, and Monochromatic each show their swatches in a grid, with the hex code printed under every color for quick reference.

03

Copy one color or all of them

Each swatch carries its own copy button, and the Copy all button puts the entire palette on your clipboard as a comma-separated list of uppercase hex codes.

Why Color Palette Generator

Common questions

What harmonies can this palette generator produce?
Five: complementary (the base plus its 180 degree opposite), analogous (neighbors at 30 degrees either side), triadic (three hues 120 degrees apart), split (the base plus hues at 150 and 210 degrees), and monochromatic (five lightness steps of one hue).
How does the tool generate color combinations from one hue?
It converts your base to HSL, rotates the hue by fixed angles, and keeps saturation and lightness untouched. That's why it can generate color combinations that feel like siblings: they differ only in hue, the property harmony rules care about.
Which generated palette works best for a website?
Analogous schemes make calm backgrounds and section colors, while a complementary pair gives you one confident accent against your main hue. Many sites combine both: analogous colors for structure, the complement reserved for buttons and links.
Does the monochromatic palette change hue at all?
No. It keeps your exact hue and produces five steps: two brightened versions, the base, and two darkened versions. That makes it ideal for card backgrounds, borders, and hover states that need to feel like one family.
Why do my generated palette colors look washed out?
The harmonies inherit the saturation of your base, so a muted base yields a muted scheme across every tab. Feed in a more saturated starting color, then tone individual swatches down afterward if needed.
Can I use this palette generator for chart series?
Triadic and split schemes work well because their hues are far apart, which keeps series distinguishable. Before shipping, run the picks through the Color Contrast Checker so labels and fills hold up against your chart background.
Is a split palette different from a complementary one?
Yes. Instead of the exact 180 degree opposite, split takes the two hues flanking it at 150 and 210 degrees. You keep most of the contrast of a complement but the pairing vibrates less, which is easier to live with in large areas.
How do I create color palette sets from one base color?
Enter a hex, then click through the five harmony tabs; each rebuilds from that base so you create color palette options without starting over. Copy a single swatch or the whole tab. The base can be typed or picked from the native swatch.
Can I make a color palette for a full landing page from one hue?
Yes. Use analogous for calm section colors and complementary for a single accent, and you can make a color palette that covers a whole landing page from one starting hue. The Copy all button on each tab grabs the set as a comma-separated hex list.
Is this a color palette generator from hex codes specifically?
Yes. Paste a hex like #6366F1 and it becomes the base for every harmony, so it's a color palette generator from hex first and foremost. The native swatch is there if you'd rather pick visually, but typed codes drive the exact same math.
Does this palette generator double as a color palette maker for brand work?
It does. As a palette generator it derives harmonies, and as a color palette maker it hands you ready hex codes for each one. Feed in your brand hue and the complementary tab gives you an accent, while analogous gives you calm supporting tones.
Is there a colour palette maker option for UK spelling?
Same tool, either spelling. Whether you searched for a colour palette maker or the US version, you get the five-tab harmony builder. Every swatch copies as an uppercase hex, and Copy all grabs the active tab in one go.
Is this a random color palette generator?
No, and that's the point. A random color palette generator throws unrelated swatches together, while this derives every color from your base hue using fixed harmony angles. That's why the results feel like a family. If you want variety, change the base color rather than rerolling.
Is it a free color palette generator, or is there a paywall?
It's a free color palette generator with no signup, no limits, and no watermark on anything you copy. As a free colour palette generator for UK spelling too, it runs in your browser. Use it as often as you like.
Can I use this color palette builder for an interior design scheme?
Yes. Pick a wall or fabric hex as the base and the harmonies act as an interior design color palette generator, suggesting accents that sit in proven relationships to it. It's a general color palette builder rather than a room planner, so treat the swatches as a starting scheme you refine by eye.
Does the color palette generator online give me rgb as well as hex?
The swatches copy as hex only, so this color palette generator online isn't a full hex and rgb palette maker on its own. To get rgb for any swatch, paste its hex into the Color Picker, which lists RGB, HSL, CMYK, and OKLCH beside the code. That two-step keeps this tool focused on harmony.
Is there an online color palette maker step I need to install?
None. The online color palette maker runs in any modern browser with nothing to download and no account. It works the same on a phone, so you can build a scheme from a base hex while you're away from your desk.
