Scope
The Neutral Field Register records finishes as relationships rather than isolated samples. A finish is assessed against substrate, ambient condition, adjacent compatibility and the likelihood that ordinary replacement will preserve the field.

FIELD / 04
Illustrative register swatches / not a commercial sample set
Method
Neutral Materials evaluates chromatic stability across the conditions in which a finish is expected to remain ordinary. Ambient continuity is relevant because the same surface may read differently as background conditions change. Placement Systems contributes substrate and persistence observations; Transitional Solutions maintains replacement consistency.
| Class | Primary consideration | Current use |
|---|---|---|
| N-1 | Stable across institutional substrates | B-400 Institutional |
| N-2 | Controlled adjacent compatibility | QuietEarth™ |
| N-3 | Replacement consistency | Meridian Standard Neutral |
| R | Retired; substrate variance exceeded tolerance | Historical reference |
