## What is Iroku?

Do you really see every color in your photos?

Iroku exposes the color truth — every color, in exact percentages. Most pickers stop at 5 to 8 swatches. Iroku shows them all, ranked and named by AI.

What's new in v2.0
- AI Insight, deeper (Gemini 2.5 Flash)
  Top 3 colors get a name, mood and harmony type on every analysis. Pro unlocks AI notes for every color, plus a "one more color" suggestion.
- Share Cards
  Export your analysis as a single Instagram Story-sized card with the Color Fingerprint and AI names. Save or share in one tap.
- Role Detection
  Every extracted color is auto-classified as background, accent or text — with WCAG contrast ratios baked in. Drop them straight into your UI.
- Harmony Score
  See your palette's harmony as a 0 to 100 score, plus the harmony type (monochrome, complementary, triadic, tetradic and 4 more).
- Two-photo Compare
  Place two images side by side and read the temperature, saturation and brightness delta. The Pro hue-wheel heatmap shows where they truly differ.

Main features
- Every color in percent (k-means plus CIE DE2000 hierarchical clustering)
- Color Fingerprint stripe bar
- AI color names, mood and palette suggestions
- Harmony score with 8 harmony types
- Role detection: background / accent / text with WCAG
- Two-photo comparison
- Share card export
- Edit colors: Hide, Isolate, Replace
- One-tap copy for HEX, RGB, HSL
- Save and revisit palettes
