TetoColor: Palette Picker

Pull vivid accent colors from any photo — even when white dominates. TetoColor goes beyond just dominant colors with theme-based extraction that surfaces the characteristic accent colors of an image. Perfect for illustrators, painters, and designers building accurate, reproducible palettes.

NEW in the latest version: palette generator (pick one color, get 5 recipes — no photo needed), palette share image (a single social-ready card), palette library (save & favorites), code export to CSS / Tailwind / SwiftUI, color-vision simulation with WCAG contrast check, and a live camera color picker.

KEY FEATURES

■ Distinctive Color Extraction (Color Theme)
Choose from 7 themes — All / Vivid / Vibrant / Deep / Light / Muted / Dark — to surface the colors that fit your purpose. Powered by Oklab perceptual scoring.

■ Eyedropper (Full-Screen Loupe)
Tap anywhere on the image to grab the exact pixel color. Full-screen zoom loupe for pixel-perfect sampling. HEX/RGB/HSL/CMYK copy in one tap.

■ Pick from Files
Beyond camera and Photos library, import images directly from Files / iCloud Drive / any cloud storage.

■ Four Extraction Algorithms
- K-Means (highest quality, default)
- Median Cut (fast, balanced)
- Octree (fastest, real-time)
- Wu's Method (highest accuracy, print-grade)

■ Region Extraction
Crop a rectangular region of the image and build a palette only from that area.

■ Up to 20 Colors per Palette
Adjustable color count with a horizontal frequency bar that shows exactly how each tone weighs in.

■ Pro Color Info
HEX, RGB, HSL, CMYK with one-tap copy to clipboard.

■ Color Harmonies (OkLCH)
Five perceptually-accurate harmonies via OkLCH hue rotation: complementary, analogous, triadic, split-complementary, tetradic.
