The <input type="color"> is a built-in HTML element that opens the operating system's native color picker. It returns a 7-character HEX string (e.g., #3B82F6) and is supported in all modern browsers. Each browser delegates to the OS-level picker — on Windows you'll see the Windows color dialog, on macOS the native Apple color picker, and on mobile devices the platform-specific color selection UI. It supports both input events (fired continuously as you drag inside the picker) and change events (fired once when the picker is dismissed).

input events fire continuously as you move the cursor or adjust sliders inside the color picker — providing real-time feedback. change events fire only once, when you finalize your selection and close/dismiss the picker. This distinction is crucial for performance: use input for live previews and change for committing the final value. Our event log above visualizes this difference in real time.

• HEX: A 6-digit hexadecimal representation (#RRGGBB), widely used in web design and CSS.
• RGB: Red, Green, Blue values from 0–255. Directly maps to how screens emit light.
• HSL: Hue (0°–360°), Saturation (0–100%), Lightness (0–100%). More intuitive for humans — adjust lightness to make a color lighter or darker.
• HSV/HSB: Hue, Saturation, Value (Brightness). Commonly used in design software and color pickers. "Value" represents the maximum of the RGB components.

WCAG (Web Content Accessibility Guidelines) defines minimum contrast ratios between text and background colors to ensure readability for users with visual impairments. AA compliance requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. AAA compliance is stricter at 7:1 and 4.5:1 respectively. Our contrast checker above instantly shows whether your selected color meets these standards against white and black backgrounds.

The EyeDropper API allows web applications to sample colors from anywhere on the user's screen — not just within the browser window. It's invoked via new EyeDropper().open() and returns an sRGBHex string. As of 2024, it is supported in Chromium-based browsers (Chrome 95+, Edge 95+) but not in Firefox or Safari. Our tool detects support automatically and shows the eye dropper button when available.

These are color harmony schemes derived from the color wheel (based on HSL hue):

• Complementary: Colors 180° apart on the wheel — maximum contrast.
• Triadic: Three colors evenly spaced at 120° intervals — vibrant and balanced.
• Analogous: Three colors within 30° of each other — harmonious and serene.
• Split Complementary: Base color + two colors adjacent to its complement — high contrast with less tension.

Designers use these schemes to create visually appealing color palettes.

Yes! The <input type="color"> is fully supported on iOS Safari and Android Chrome. On mobile, tapping the color input opens the platform-native color picker. Our tool is fully responsive and optimized for touch interaction — the large preview area and tappable swatches work seamlessly on small screens.

Every color format card (HEX, RGB, HSL, HSV) has a Copy button. Click it to copy the exact value to your clipboard. The button briefly shows a checkmark to confirm the copy. You can also click any color swatch in the history or presets section to instantly load that color. All clipboard operations use the modern navigator.clipboard.writeText() API.
