Find the paint mix hiding inside any photo.

Military service trains you to read terrain, light, and distance with precision. Those same skills make you exceptional at landscape painting — you see what others miss.

Police work demands hyperawareness and split-second decisions. Painting is the opposite — it teaches you to slow down, breathe, and choose deliberately.

Paramedics see the full spectrum of human experience. Painting gives a language for what words can't hold.

Fire crews know how to read the landscape in seconds. That spatial awareness makes you a natural at composition.

If you don't understand what your advocate is telling you — or you feel unheard, confused, dismissed, or pressured — you are allowed to find another advocate you can actually work with.

Not all advocates are equal. Some are excellent. Some may not fully understand your situation, your injuries, or how to communicate in a way that makes sense to you. That does not mean your case is weak or that you should give up.

Many veterans are eventually approved after initially being refused. Do not assume an early refusal means you are not entitled to support.

Tip: Sample in the mid-tones first. Nail the middle value, then adjust lighter or darker.

Percentages are ratios, not millilitres. 60% + 40% means 3 parts to 2 parts.

AI critique uses the internet. Everything else works offline.

Stocktake has two modes — Artist (track your own paints) and Art Teacher (plan classes, orders and lessons).

Why Australian brands? The shopping list links to Eckersley's, Jacksons Drawing Supplies, and Mont Marte — verified May 2026 pricing (snapshot — verify before ordering). Chromacryl is the recommended default (3.27¢/ml, made in NSW). Always verify current prices and availability directly with the supplier before ordering.

On the recipe page (page 2), a toggle at the top switches between two recipe modes.

Tip for teachers: Use this before each lesson to confirm your current stock can still deliver the colours you planned to teach. If the score drops significantly, the lesson may need adjusting or a restock first.

SfumatoART uses Claude (by Anthropic) for all AI features. Here's what each tool does and how it works.

Privacy: Photos and text sent to AI tools are processed by Anthropic's API and are subject to Anthropic's privacy policy. No data is stored on SfumatoART's servers. All other app data (paints, palettes, projects) stays on your device only.

Why does it take a few seconds? The AI reads your image or text carefully before responding — like a teacher taking a moment to think before giving feedback. The quality is worth the wait.

SfumatoART converts colours into CIE L*a*b* colour space — a mathematical model that describes colour the way human vision works, not the way screens display it. It then measures the perceptual distance (delta-E) between your sampled colour and each paint in the database.

Why not spectral mixing (Kubelka-Munk)? Some professional colour tools use a spectral model that predicts exactly how pigments mix physically. This is more accurate for paint mixing ratios — but it requires laboratory-measured paint data (reflectance curves) that is not publicly available for Australian student-grade acrylics like Chromacryl. Delta-E gives excellent practical results for the colour-matching purpose SfumatoART is designed for.

The AI critique in SfumatoART follows Feldman's four-stage critique method, the most widely used structured art feedback framework in English-speaking curricula.

Skill levels follow Bloom's Taxonomy — the language register shifts from remembering and understanding (Beginner) through applying and analysing (Intermediate) to evaluating and creating (Advanced). This is the same cognitive progression Australian curriculum documents use for progression descriptors.

Two Stars and a Wish (the optional beginner feedback format) is a formative assessment tool from Black & Wiliam (1998) Inside the Black Box — one of the most-cited educational research papers of the last 30 years. It produces specific positive reinforcement plus one focused improvement point, which is proven to be more actionable for learners than a single grade or mark.

ACARA V9 alignment: The Responding strand of the Australian Visual Arts curriculum (F–10) maps directly to Feldman stages 1–3. Critique prompts are worded to align with the elaborations at each year band.

SfumatoART is built on published research and curriculum frameworks. The sources below underpin the colour science, critique methodology, and educational design in the app.

SfumatoART is an independent tool. It has no affiliation with Anthropic, ACARA, DVA, RSL, or the referenced publishers beyond using their publicly available frameworks and APIs.

These are diagnostic tools. You will rarely need them — but when something feels wrong, this is where to look.

The debug log records every toast, click, and error inside SfumatoART. Useful when reporting a bug.

The log lives only in memory and resets when you reload the page. It contains your timestamps, taps, and any error messages — no painting data.

The Admin tab is for developer tools — viewing app state, clearing data, etc. It is protected by a password.

If even the default doesn't work, your browser may be running an old cached copy. Pull down to refresh, or close and reopen the app.

• Every toast notification you saw, with timestamp
• Every click — element id and screen position
• Any JavaScript error or unhandled promise rejection
• console.log / warn / error / info messages

The log stays in memory — capped at the last 500 entries. Nothing is uploaded anywhere automatically.
