Iroku — AI Color Truth

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.
