SAMPLE ANY COLOR
• Drag to sample the exact pixel, with a magnifier loupe for precision.
• Instant HEX, RGB, HSL, and CMYK, plus a color name and hue family.
• Complementary, analogous, and triadic harmonies from any color.
CONTRAST & ACCESSIBILITY
• WCAG 2.1 contrast with clear AA / AAA pass or fail.
• APCA (the WCAG 3 preview) and ΔE for the full picture.
