Palette record · development evidence
What is the official MARD 221 RGB reference?
It is a versioned digital reference transcribed from the supplier's official spreadsheet. It contains 221 MARD codes: 220 numeric RGB/HEX entries plus H1, identified as Transparent. It supports software development but does not prove a physical colour match.

Total: 221 development colour codes.
How was the development record created?
- Record the supplier codes.
The A1–H23 and M1–M15 code ranges were transcribed into CSV and JSON records.
- Import the official digital reference.
RGB/HEX values come from the supplier spreadsheet. H1 is recorded as Transparent and has no official numeric RGB.
- Attach evidence metadata.
Every row records its source, calibration status and production eligibility.
- Fail closed.
Uncalibrated records are excluded from the production palette by code.
Is this palette physically colour accurate?
No. Supplier RGB defines the intended digital reference, but it is not a physical Lab or spectral measurement of the bead batch. Screen appearance also depends on colour profile and viewing conditions.

What changes after physical samples arrive?
The legacy screenshot-derived record remains immutable for audit history. Controlled measurements will create a new physical palette version with Lab/spectral values, batch identifiers, capture conditions and reviewed production flags.
A future identifier may follow a pattern such asMARD-221-UKENN-202608A-V1, but no physical version exists yet.
