About the Color Palette Generator

The Color Palette Generator builds a coordinated set of colours from a single base colour. It produces several classic colour-theory schemes — analogous, complementary, triadic, monochromatic, and shades — so you can explore harmonious combinations without guessing.

Each generated colour is shown with its HEX value, and the CSS for the whole palette can be copied in one click. It runs entirely in your browser.

How to use the Color Palette Generator

1. 1Open the Color Palette Generator tab.
2. 2Pick a base colour using the colour picker or by entering a HEX value.
3. 3Choose a scheme (analogous, complementary, triadic, monochromatic, or shades).
4. 4Copy the HEX values or the generated CSS for your stylesheet.

How the Color Palette Generator works

For the Color Palette Generator specifically, it builds a coordinated set of colours from a single base colour. Design tools generate ready-to-paste CSS from the values you set, using standard web-platform features, and every value can be copied to the clipboard with a single click. The Color Palette Generator applies color theory — analogous (adjacent hues on the wheel), complementary (opposite hues), triadic (three evenly spaced hues), monochromatic (varying lightness), and shades — by converting your base color to HSL and rotating the hue or adjusting lightness. The Gradient Generator outputs linear, radial, and conic gradient syntax with adjustable color stops and angle. The Box Shadow Generator composes multi-layer box-shadow strings; layering a tight, dark shadow close to the element with a larger, lighter one further away produces more realistic elevation than a single heavy shadow. The Border Radius Generator outputs per-corner border-radius values, so you can create uniform rounded rectangles or asymmetric pill and leaf shapes. The Contrast Checker computes the WCAG contrast ratio: it converts both foreground and background colors to relative luminance via the sRGB transfer function and applies the formula (L1+0.05)/(L2+0.05), then reports pass or fail for AA and AAA at normal and large text sizes. The Font Pairing tool curates free, open-source Google Fonts pairings — typically a display or serif heading with a neutral body font — and emits the @import snippet and font-family rules you need to add them to a project. Nothing is uploaded; all generation is local.

How this tool handles your data. This tool runs entirely in your browser. The values you set are used to generate ready-to-paste CSS or to preview a result, and nothing is uploaded. Every generated value can be copied to your clipboard with a single click and pasted straight into a stylesheet.

Supported formats & limitations. Every design tool outputs ready-to-paste CSS you can copy with one click. The Contrast Checker reports WCAG AA and AAA pass or fail at normal and large text sizes. Font pairings use free, open-source Google Fonts and include the CSS import snippet you need to add them to a project.

Practical workflow. In practice, you work through a short sequence: 1. Open the Color Palette Generator tab 2. Pick a base colour using the colour picker or by entering a HEX value 3. Choose a scheme (analogous, complementary, triadic, monochromatic, or shades) 4. Copy the HEX values or the generated CSS for your stylesheet. It is well suited to building a brand colour system from one primary colour; exploring accent colours for buttons and highlights; generating a consistent palette for a new interface.

Best practice. Aim for at least AA contrast (4.5:1 for normal text) and pick a heading/body pairing that contrasts in weight or style so headings stand out without competing.

Tips & common pitfalls. With the Color Palette Generator in particular, building a brand colour system from one primary colour. Aim for at least AA contrast (4.5:1 for normal text) and pick a heading/body pairing that contrasts in weight or style so headings stand out without competing. For natural-looking elevation, layer two box shadows — a tight dark one close to the element and a larger lighter one further away — rather than a single heavy shadow. Copy the generated CSS straight into your stylesheet. The Font Pairing tool emits the @import snippet and font-family rules you need to add free Google Fonts to a project.

Troubleshooting

The first thing to know about the Color Palette Generator: analogous colours sit next to each other on the wheel and feel calm and unified; complementary colours sit opposite each other and create strong contrast; triadic uses three evenly spaced colours for a vibrant, balanced look. If a generated CSS does not apply, copy the full block including the property name and semicolon, and confirm the selector targets your element. If the contrast checker fails AA, lighten or darken one colour until the ratio reaches 4.5:1 for normal text. If a gradient looks banded, add an intermediate colour stop. If a box shadow looks harsh, replace the single heavy shadow with two layered ones — a tight dark one close and a larger lighter one further away. If a font pairing does not load, paste the @import snippet at the very top of your stylesheet, before any other rules. If the border radius looks uneven, set each corner separately rather than relying on the shorthand.
