About this app

Can't mix that color with the paints you already have? Now you can.

📷 Take a photo and tap the color you want — the app reverse-calculates a recipe using ONLY the paints you own. No extra buying. Match box art, real cars or other builds to your own paints.

Custom paint colors are impossible to recreate unless you record them. Pick real hobby paints by name (Mr.Color, GX, Tamiya, Gaia, Aqueous and more) and enter the ratio — the app instantly calculates the mix ratio (%), the exact amount of each paint (drops/ml), and an estimated result color (physically-based Kubelka–Munk subtractive mixing).

Features:
• 🧰 Recreate a target color using ONLY the paints you own — automatic reverse-calc
• 📷 Pick a color from a photo, camera or swatch and get a matching recipe
• Pick real paints by name, or add your own colors
• 3D preview of the finished color
• Auto-scale a ratio like "3 white : 1 blue" to any amount
• Save, copy & share recipes; printable paint labels
• Fully on-device, no sign-up, offline-ready, 8 languages

Pro (one-time): unlimited recipe saving, backup export/restore, printable labels, no ads.

Note: colors are an estimate — always test on scrap first.
