The palette, in short
- Core: black and white — with warm beiges standing in for grey. Ash deliberately avoids cold grey.
- Lead accent: Periwinkle — bold enough to be memorable, soft enough to be safe. It replaced the book’s Lavender Blue

How we got here
The 2026 palette is a correction, and the book is honest about it. The earlier identity leaned on heavy beige and a muted purple — warm, but murky, not punchy, and spread across too many colors to build recognition. What was missing: boldness, a signature tone with depth and appeal across genders, and a sense of joy. The answer was restraint — a black-and-white core with periwinkle in the lead.

- Warm over cold — parchment, not grey.
- Restraint by default — color earns its place; the canvas stays calm.
- Never rely on color alone to carry meaning — see Robustness & Readability.
