Ledger.

One institutional identity.
Six carefully balanced expressions.

A source-faithful palette for the OBLOC academy, research workspaces, and Cryptobill Studio. Explore the mixtures. Inspect the tokens. Keep presentation separate from proof.

ACTIVE PRESETIntellectual Ledger

02 / IN CONTEXT

An educational interface,
not a promotional skin.

Semantic colors, legible source code, reserved accents,
and explicit experiment states.

RESEARCH / DESIGN LAB

Understand the cryptobill.

◇ Nonredeemable study
Presentation text only. Not an issuance record.

No theme-selection note recorded.

TYPOGRAPHY

A scholarly voice.

Serif display headings. Clear system sans-serif reading text. Monospaced evidence and identifiers.

STATUS LANGUAGE

Meaning before color.

✓ Pair checked△ Needs review× Capability blocked

Icons and explicit words carry status. Mint and gold never imply a valid signature, ownership, or redemption.

INTERACTION

Quiet, not invisible.

Visible focus, underlined links, bounded motion, and comfortable control targets.

03 / COLOR MIXTURES

Make the relationship explicit.

Channel interpolation and interface-area allocation
are different operations. Neither is a physical ink recipe.

The six shipped presets use fixed sRGB hex values. Experimental mixtures do not silently overwrite their tested semantic roles.

Integration and boundaries →

Keep the bill immutable

A theme changes website presentation, not canonical TIFF samples, encoded bit planes, hashes, signatures, or frozen run specifications. Never apply theme-driven filters to the canonical export.

Bill artwork is a separate design input. Changing it requires an explicit new draft and fresh encoding and verification.

Design and artifact rules →

Inspect, do not assume

108 configured color pairs have an included contrast calculation. This is not a whole-platform accessibility certification.

Gradients, translucent layers, custom mixtures, images, motion, keyboard behavior, and real application content need their own assessment.
