VINTAGE SCIENTIFIC ILLUSTRATION

VISUAL STYLE: Vintage scientific illustration — the visual tradition of 19th and early 20th century scientific publishing. Steel engraving, lithography, and hand-coloured plates. The discipline of showing exactly what is there, and not one thing more.

COLOUR PALETTE: The specific palette of hand-coloured scientific illustration. The warm ivory (#FFFFF0) of engraving paper. Delicate watercolour tints over engraved lines: soft botanical green (#7DAA72), pale blue (#B8D4E8), warm ochre (#C8A86B). The deep black (#1A1A1A) of steel engraving lines carrying all the structural information. The colour adds only enough to identify and distinguish — it does not describe light and shadow.

ENGRAVING TECHNIQUE: Fine parallel hatching lines for tonal areas. Cross-hatching for deepest shadow. The lines follow the surface form — contour hatching on rounded objects, parallel lines on flat planes. Each mark is a decision.

BOTANICAL PLATES: Plants shown with roots, stem, leaf, flower, and seed — the complete life cycle on one plate. Details extracted and enlarged in inset circles. Latin binomial in italic type beneath.

ANATOMICAL PLATES: Cross-sections that reveal internal structure. Numbered callouts referring to a key. Multiple views — plan, elevation, section — on a single plate.

LETTERING: Copper plate or lithographic italic — the specific hand of a Victorian engraver working on metal or stone. Precise and formal.

No photographs. No modern printing effects. No digital flatness. Only engraved line, careful watercolour tint, and the observational precision of a century of scientific illustration throughout.
