Color Palette Generator

Five swatches at a time, derived from one random hue using complementary, triadic, analogous or monochromatic spacing around the color wheel, or scattered independently in random mode.

What is the Color Palette Generator?

Color harmony is mostly arithmetic on a circle: hues sit at degrees from 0 to 359, and the classic schemes are simply fixed rotations away from a starting point. Complementary sits at 180 degrees, triadic at 120, analogous at 30, while monochromatic never moves the hue at all and varies lightness instead. This page rolls a random base hue, applies whichever rotation you picked, converts the resulting HSL values to hex, and shows each color with its RGB equivalent. The base hue is always random, so there is no field for entering a brand color to build around.

Key Features

• Five harmony modes: random, complementary, triadic, analogous and monochromatic
• Each swatch shows its hex code and matching RGB triplet
• Click any band or card to copy that single hex
• Export CSS saves palette.css holding five custom properties
• A history strip keeps your last ten palettes clickable

Common Use Cases

• Finding a starting hue for a landing page before opening a design tool
• Picking five distinguishable series colors for a chart or dashboard
• Filling in accent, hover and muted shades around a chosen brand color
• Breaking the habit of reaching for the same blue on every project

How to Use the Color Palette Generator

1. Choose a harmony mode; selecting one immediately rolls a fresh palette.
2. Press Generate Palette repeatedly until a set you like lands.
3. Click a band or an info card to copy that hex code on its own.
4. Use Copy All HEX for the whole set, or Export CSS to download palette.css.
5. Click any earlier strip under History to bring that palette back.

Tips for Best Results

• There is no lock control, so copy a color you like before generating again.
• Monochromatic steps lightness from 25 to 85 percent, making it the best source of text-on-background pairs.
• Random mode ignores harmony entirely, drawing all five hues independently of one another.
• Nothing here measures contrast ratio, so test any text pairing against WCAG before shipping it.

Why Use WiserWork's Color Palette Generator?

This page does the color-wheel arithmetic honestly and quickly: rotate a hue by 180, 120 or 30 degrees, fix the saturation and lightness, and read the result as hex. What it will not do is let you pick the starting hue or tell you whether a pairing is readable, so it works better as a starting point than as a final decision. Nothing is uploaded, and no palette persists beyond the ten held in memory.

Who Uses the Color Palette Generator?

Front-end developers who need five defensible colors before a designer is free, hobbyists choosing a scheme for a slide deck, a chart or a room, and anyone teaching color theory who wants complementary and triadic spacing shown side by side. Illustrators also use random mode as a nudge out of a familiar palette.

Frequently Asked Questions

Can I enter my own base color?

No. Every palette starts from a hue chosen at random, so there is no input for a brand hex. Generate until something lands near your target, then adjust the exported values by hand.

How is the complementary palette built?

Complementary colors sit opposite each other on the wheel. The tool renders the base hue and the hue 180 degrees away at two saturation and lightness settings each, plus one deeper, more saturated version of the base.

What does triadic mode produce?

Three hues spaced 120 degrees apart, each in a stronger and a lighter version. That would be six swatches, so the set is trimmed to five and the third hue ends up with only one.

How does analogous mode space its colors?

It takes the base hue and steps 30 degrees either side twice, giving minus 60, minus 30, base, plus 30 and plus 60. All five sit at 60 percent saturation and 50 percent lightness.

What varies in a monochromatic palette?

Only lightness. One hue is held at 50 percent saturation while lightness rises in steps of 15, from 25 percent through to 85 percent.

Does it check color contrast for accessibility?

No, there is no contrast ratio or WCAG check anywhere in the tool. Run any text-and-background combination through a dedicated contrast checker before using it.

Can I lock a swatch I like and reroll the others?

No. There is no lock feature; every press of Generate Palette replaces all five colors. Copy the hex you want to keep first, or find the palette again in History.

Does the History strip survive a page reload?

No. It holds the ten most recent palettes in memory only, so refreshing or closing the tab clears it.

What is inside the exported CSS file?

A single :root block declaring --color-1 through --color-5 with the current hex values, saved as palette.css. Paste it straight into a stylesheet and reference the variables.

Why show hex and RGB but not HSL?

The colors are generated in HSL internally, then converted for display. Only the hex code and its RGB equivalent are shown, so the hue and saturation numbers behind a swatch are not exposed.

Harmony rules are a shortcut, not a verdict, and the palette that survives contact with real content usually needs a hand-tuned tweak. Roll a few sets here, copy what catches your eye, then check the contrast before it reaches production.
