HEX Color Picker – Free Online Tool

HEX Color Picker is a minimal swatch + HEX input combo. Pick visually, type a HEX directly, or paste a 3-digit shorthand — the RGB equivalent updates in real time. Best for designers who want the simplest possible "give me the HEX" workflow.

• Instant results — no waiting on a server or upload progress bar
• Touch-friendly UI, fine on phones for on-the-go edits
• No registration, account, or installation required
• WCAG contrast checks calculated correctly for AA and AAA, both text and large text
• Outputs valid CSS, Tailwind, and design-tool color formats side-by-side

1. Pick a colour with the native picker or paste a HEX code (3 or 6 digits)
2. Read the equivalent RGB triplet displayed live
3. Copy the HEX value (uppercased) when you're ready

• Quickly grabbing a HEX for CSS without the noise of HSL/CMYK fields
• Validating a HEX from a brand guide (catches typos like #GG0000)
• Educational demos showing how HEX maps to RGB channels

Native picker shows a colour but my typed HEX is rejected.

Manual input must be exactly 3 or 6 hex digits with optional #. Trailing whitespace or non-hex characters cause the field to fall back to the last valid swatch.
