## 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

— PRICING —
Included: the full picker, photo sampling, harmony palettes, the WCAG contrast checker, and one-tap HEX copying.
Hexnut Pro is a one-time in-app purchase — not a subscription — and adds the Saved tab with color history and pinned favorites, plus one-tap copying of RGB, HSL, HSB, SwiftUI Color, UIKit UIColor, and CSS.
