A paint studio for miniature painters

Work out your scheme, set up your lighting, and match colours to the paints already sitting on your shelf. All of it happens before the brush ever touches the model.

Two studio tools, open to everyone

No sign-up, no download, no upload. They run entirely on your machine, so your models stay yours.

💡 Light Studio

Drop in your STL and light it the way a photographer would. Preview NMM (non-metallic metal) and OSL (object-source lighting) with real cast shadows, so you can see where every highlight and shadow will land before you commit a drop of paint.

  • Silver and gold NMM, glowing OSL, matte through chrome. Each one is a single click.
  • Paint regions straight onto the model, each with its own colour and finish
  • Turn a painted region into a light source: lava, runes, a glowing blade
  • Save your lighting rigs and grab reference renders

🧩 Assembly Workbench

Printed a multi-part kit? Drag the parts in, nudge each one roughly where it belongs, and Chromatory snaps the mating surfaces together for you. Then export the whole thing as one merged STL, ready for the slicer.

  • Load every part of a kit. No triangle limit, and none of it leaves your device.
  • Automatic surface-registration snapping lines the parts up exactly
  • One drag does one thing: it moves or it rotates, never both at once
  • Export a single watertight STL that's ready to print

The full studio

Built around your paints

Chromatory knows what's actually in your paint drawer, so every match, mix and scheme it suggests is something you could sit down and paint tonight.

💡

Light Studio

Place your lights, preview NMM and OSL with true cast shadows, and paint per-region materials anywhere from matte to chrome.

📷

Copy a mini from a photo

Point it at a painted miniature you love. Chromatory reads each area and works out a step-by-step scheme using the paints you already own.

🌗

Shadow & highlight guide

Give it a scheme photo and a lighting render. For each element it hands back the shadow, midtone and highlight paints, and shows you where each one falls.

🎯

Colour match & mixing

Real colour science (CIEDE2000 and Kubelka-Munk) finds the closest paint you own, or the mix that gets you there.

🗄️

Paint inventory

Catalogue your collection with swatch photos, and name a paint straight from a snap of the bottle.

🤖

AI painting coach

Advice, a painting log and scheme mockups, all built on the paints you really have. It runs locally or in the cloud, and turns off completely if that's what you'd rather.

🔒

Local-first and private

Everything runs on your own PC. Your data, photos and models stay with you. Pair your phone or browser to it whenever you want the bench in your hand.

🔒

Your files stay yours

The browser tools run entirely on your device, so models are never uploaded anywhere. The full app is local-first as well. It lives on your PC, keeps your library in your hands, and only talks to the cloud when you ask it to.
