Soil Colour Analyser
Upload a field photo of soil. AI vision identifies the dominant colour and returns Munsell notation, hex, RGB, and a pedological interpretation calibrated for Australian soils.

Verification: AI colour matching should always be confirmed against a physical Munsell chart for formal soil description. Accuracy varies with lighting, moisture state, and image quality.
Munsell Soil Colour Charts: The standard reference for soil colour description. Munsell Soil Colour Book ↗ — USDA digital reference (PDF) ↗
Australian standards: Munsell notation is the accepted standard under the Australian Soil and Land Survey Field Handbook (3rd ed., National Committee on Soil and Terrain, 2009) and the NCST National Soil Data Protocol. Record colour at both moist and dry states where possible — Australian soils, particularly Vertosols, Chromosols, and Sodosols, can shift 1–2 value units and 1–2 chroma units between states.
