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.
Drag the saturation/brightness field and hue rail, fine-tune R, G, and B, or just type a hex code. Load a photo and drag the loupe to read the exact hex of any pixel.
WHAT MAKES HEXNUT DIFFERENT
- Precision picker
A saturation/brightness field, a hue rail, 0–255 R/G/B fields, and direct hex entry all drive the same live preview. - Sample from any photo
Drag the loupe across a photo and read the exact hex and RGB of the pixel beneath it. A generated sample image is already loaded, so the tab is useful the moment you open it. - Harmony palettes
Generate complementary, analogous, triadic, split-complementary, and monochromatic sets from the color you are holding. - Contrast you can trust
See the WCAG contrast ratio against white and black with AA / AAA badges, so you can judge readability before you commit to a color. - Every format, one tap
HEX, RGB, HSL, HSB, SwiftUI Color, UIKit UIColor, and a ready-to-paste CSS declaration. Tap a row to copy it. - Fully offline
No account, no ads, no tracking, no network calls. Colors you save stay in local storage on your device.
WHO IS HEXNUT FOR?
- Designers matching a color they spotted in a screenshot, a mockup, or the real world
- iOS developers who want SwiftUI Color or UIColor code without doing the math
- Web developers who need a hex, an rgb() value, or a CSS declaration to paste
- Anyone who wants a color picker that never asks for an account
