Hexnut
About
Hexnut is the fast, no-nonsense hex color picker. It does one job cleanly: get exact color codes and copy them in a tap. No accounts, no ads, no tracking — and it works fully offline.
PICK WITH PRECISION Drag the saturation/brightness field and hue rail, fine-tune R, G, B, or just type a hex code. A live preview shows your color instantly.
SAMPLE FROM ANY PHOTO Load a photo and drag the loupe to read the exact hex of any pixel. Perfect for matching a color you spotted in a design, a screenshot, or the real world.
EVERY FORMAT, ONE TAP HEX, RGB, HSL, HSB, plus ready-to-paste SwiftUI Color and UIKit UIColor code. Tap any row to copy.
CHECK CONTRAST See the WCAG contrast ratio against white and black with AA / AAA pass badges — handy for accessible, readable color choices.
SAVE YOUR COLORS Every color you pick is kept in a local history. Pin the ones you love. Nothing ever leaves your device.
Built with native Apple frameworks. Universal app for iPhone and iPad.
