About this app
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.

Baseline captured. Growth appears after the crawler observes a changed rating count.
Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
