Colour sub-palettes

Summary

The sub-palettes page: six curated 3x3 colour blocks pulled from the extended palette, laid out along an analogous-to-complementary spectrum, intended for graphics, patterns, and diagrams.

Visual description

Standard layout: cream left column with section number "2.5.4 Sub-palettes" and two short lines explaining that limited sub-palettes can be built from the extended palette and work well on graphics, patterns, and diagrams; navigation list lower-left with Colour bolded. The white panel shows six 3x3 swatch blocks, three in a top row and three in a bottom row. Each cell is a coded swatch (e.g. 4AA, 5AA, 6A / 4B, 5B, 6B / 4D, 5D, 6D), so each block is a self-contained nine-colour set. A horizontal arrow between the two rows is labelled "Analogous" at the left and "Complimentary" at the right, positioning the blocks from harmonious to contrasting. The cream footer carries copyright, document title, and "Version 01".

Key takeaway

Curating ready-made nine-colour sets from a large palette and organising them on an analogous-to-complementary axis, so a designer picks a whole coherent set (and a harmony level) instead of assembling colours one by one. The 3x3 block is a tidy unit for a palette that maps directly to a small graphic or chart.

Reuse notes

A reusable sub-palette page for brands whose extended palette is too big to use raw. Best for systems that produce a lot of data visualisation, illustration, or patterns and need pre-vetted, limited sets. The analogous-to-complementary arrow is a useful framing for choosing mood. Pairs with the extended palette it draws from (slide 52) and the pairings page (slide 53).
