Fieldmix: a painting coach that mixes from the paints you actually own

Description and use

Fieldmix automatically proposes color shapes and mixing recipes using only the user’s paints, and guides the user step‑by‑step, reducing setup time for painting.

Problem

Choosing paint colors for a painting is a bottleneck, especially when limited to the paints one owns.

Outcome

Fieldmix reduces the color‑selection bottleneck by automatically generating paint‑mix recipes from the user’s own palette and guiding the painting process through audio instructions.

Workflow

• Photograph the scene or pre‑drawn canvas
• Tap the paints you own to create a palette
• For a pre‑drawn canvas tap "Suggest colors" to get a color for each shape
• For a photo the app splits the image into numbered color shapes
• Each shape receives a mixing recipe made only from the tapped paints
• Gemma 4 labels shapes and plans the painting order
• The phone reads each step aloud with the recipe
• The user taps "Next" to proceed to the next step

Evidence

Fieldmix splits the picture into a few color shapes, works out how to mix each one from only your paints, and talks you through the painting step by step

The model never does color math

Deterministic code does all the color: k‑means in CIELAB finds the color shapes; spectral.js (Kubelka‑Munk) mixes paints the way pigment mixes; CIEDE2000 scores how close each mix gets.
