$0.01 — pay-per-hue. A canvas where narrative depth is gated by the spectrum. Illustrators publish grayscale drafts; users unlock specific color layers and narrative shifts in real-time. Each tap to 'fill' a scene or progress the palette triggers a 0.01 USDC HTS transfer transfer. The artist is paid per impression and per immersion, turning visual storytelling into a metered, high-fidelity experience for collectors and AI training sets looking for human emotional-color mapping.

The primitive.

full primer →

Access to the color narrative art engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so painters — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveMoving from static NFTs to 'pay-per-reveal' mechanics turns the aesthetic experience into a high-frequency revenue stream. By metering the color evolution, we create a new primitive for digital art consumption where the audience pays to witness the metamorphosis.
