v1.0 (October 2026). First registration on the Workhorse token system. Every value is TRANSCRIBED from AACT Brand Guidelines Version 1.0 (58 pages, (c) 2014 American Chemical Society; Dropbox Projects/AACT/4_Client Provided Assets/1_Brand/aact_brand_guidelines.pdf), the two .ase swatch files beside it, and the logo artwork AACT_R_rgb (3_Assets/brand). The version number is the book's. Where the book's own web colors fail WCAG 2.1 AA at the sizes the book assigns them, the system names an accessible role taken from the book's own palette and records the deviation in place; none of those deviations is approved by AACT yet, and the book routes every unlisted usage through the AACT brand representative.
