Recorded data

The original Brush import is a synthetic color grid. Sketch, Junior and Fineliner imports sampled chart images and used site-assigned codes or names. These records do not establish manufacturer product identities. Existing color values and URLs are preserved.

Computed data

RGB display values, previews, and colour relationships are calculated by the website from each stored HEX reference.

Physical colour

A screen preview does not replace a physical swatch; paper, layering, nib condition, lighting, and the display can all change appearance.

Unknowns

This catalog does not establish manufacturing tolerances, laboratory measurements, batch variation, current availability, discontinued or renamed codes, or complete manufacturer product-line coverage.
