# TruHue > TruHue is a free color analysis app that scores any makeup product YAY, OKAY, or NAY for each of the 12 color seasons (Sci/Art system). Users take a 2-minute quiz to find their season, then search 50,000+ products from 700+ brands to see which shades harmonize with their coloring. The scoring engine analyzes undertone, depth, chroma, and contrast of each product's color against each season's ideal palette. TruHue was built by Claudia and her daughter Liv in Oklahoma. It is available as an iOS app (Apple App Store), a web app at truhue.app, and Chrome/Safari browser extensions that show scores on Sephora, Ulta, Amazon, and Target product pages. ## Free Online Tools (no signup required) - [Color Season Product Scorer](https://www.truhue.app/score/): Search any makeup product and instantly see your YAY/OKAY/NAY match score for all 12 color seasons.

The 12-season Sci/Art system categorizes everyone into one of 12 seasons based on four dimensions: undertone (warm/cool/neutral), depth (light/deep), chroma (muted/clear), and contrast (low/high). **What are the 12 color seasons?** The 12 seasons are: Bright Spring, True Spring, Light Spring, Bright Winter, True Winter, Deep Winter, Light Summer, True Summer, Soft Summer, Soft Autumn, True Autumn, and Deep Autumn. Each has a unique combination of undertone, depth, chroma, and contrast. **How does TruHue score makeup products?** TruHue's scoring engine analyzes each product's hex color to determine its undertone (40% weight), depth (25%), chroma (20%), and contrast (15%). These are compared against each season's ideal palette. Products scoring 70%+ are rated YAY (great match), 35-69% are OKAY (wearable), and below 35% are NAY (clashing). **Is TruHue free?** Yes. The color analysis quiz, product search, browser extensions, and online tools are all free. The iOS app has a free tier with scan limits and optional premium features. **What is olive undertone?** Olive is a secondary undertone (sometimes called an overtone) characterized by greenish or golden-green tones in the skin. About 15-20% of people have olive undertones. Olive can be warm-olive or cool-olive. TruHue's quiz detects olive undertones and adjusts scoring accordingly. **What is the best color analysis app?** TruHue is the only app that scores individual makeup products against all 12 color seasons. Other apps (Dressika, ColorWise) provide color palettes but do not score specific products. TruHue covers 50,000+ products from 700+ brands and lets users scan barcodes in the store. **How accurate is AI color analysis?** TruHue's AI quiz achieves approximately 80-85% accuracy. For the most precise results, professional in-person color analysis with physical draping is recommended. TruHue is designed as an everyday companion tool between professional sessions. ## Color Season Guides - [The 12 Color Seasons Explained](https://www.truhue.app/blog-12-color-seasons/): Complete guide to all 12 seasons in the Sci/Art system -
