TintPaint

Pigment Simulator

Technical breakdown of TintPaint

TintPaint is built as a Unity-based paint simulation, not just a normal digital color picker. The idea is to model paint as a physical material: pigment, base, finish, wetness, opacity, drying, film buildup, and how it reacts to the surface underneath.

At the mixing level, the app has a paint bucket that combines colorants, base paint, finish, and drying behavior into one paint material. The goal is for color mixing to behave more like real pigments than simple RGB blending.

At the surface level, the paint board runs on the GPU. Each brush stroke writes into multiple simulation fields: pigment amount, material properties, wetness, dryness, height/thickness, movement, and medium behavior. That lets paint feel wet, build up, dry down, smudge, or resist rework.

MacOS Users

Tint Paint is not signed with an Apple Developer certificate, macOS will show a security warning and block the app from opening.

To fix this, open Terminal and run:

xattr -r -d com.apple.quarantine "/path/to/TintPaint.app"

Then double-click the app as normal

Alternatively, go to System Settings → Privacy & Security and click Open Anyway after attempting to launch it once.
