Precision Color Picker

Interactive HSL sliders with a dynamic preview circle and animated hue ring. Type hex codes directly or fine-tune with Hue, Saturation, and Lightness controls. View and copy colors in HEX, RGB, and HSL formats with a single click.

Pick Colors from Any Page

Activate the eyedropper tool and capture any color from any webpage. A real-time magnified preview follows your cursor showing the exact hex value. Click to capture — the color instantly loads into the picker.

Smart Palette Generator

Generate professional color harmonies with 6 modes: Complementary, Analogous, Triadic, Split-Complementary, Square, and Monochromatic. Save palettes to your library or export as CSS custom properties with one click.

Visual Gradient Builder

Design stunning CSS gradients with support for Linear, Radial, and Conic types. Adjust angle and color stops visually with live preview. Copy production-ready CSS code with a single click.

WCAG Contrast Checker

Verify color accessibility against WCAG 2.1 standards. Enter foreground and background colors to see the contrast ratio with clear Pass/Fail indicators for AA and AAA compliance at both normal and large text sizes.
