Overview

CSS Color Generator is a visual tool for generating CSS colour code. Interact with a colour picker and an alpha slider and instantly get HEX, 8-digit HEX (with alpha), RGB, RGBA and CSS custom-property code, letting front-end developers and designers assemble and copy CSS-conforming colours quickly.

How to Use This Tool

Step 1 — pick a colour with the native colour picker (click the swatch) or type a HEX value into the box. Step 2 — drag the Alpha slider to change transparency (0 fully transparent, 1 fully opaque); the swatch below is drawn on a checkered background so you can see the transparent effect. Step 3 — click one of the preset swatches to fill in a common theme colour. Step 4 — in the "CSS code" panel each format has a "Copy" button; the result is ready to paste into a CSS file or component style.

Common Use Cases

Front-end developers debugging component styles produce alpha-channel colours quickly (such as rgba(0, 229, 255, 0.5)); design-system teams standardise a palette and emit CSS-variable code; adjust the tint of an overlay, mask or hover state; convert colours from a design spec into full CSS code; iterate on colour choices while building theme switching.

Technical Details

8-digit HEX uses the #RRGGBBAA form where AA is the hex representation of alpha (0.5 → 7f) and is supported in CSS Color Module Level 4. RGBA’s alpha uses a decimal 0-1. The CSS variable snippet uses the placeholder --color — rename it as needed. HEX supports auto-expanding 3-digit into 6-digit. The preset swatches are a vibrant collection commonly used in design.

Privacy & Security

All colour generation happens locally in your browser and no network requests are made.
