The Accessible Palette Workbook

The PaletteUI workbook for turning one brand color into a ten-step UI scale with every text pairing, state and overlay checked against WCAG

The tools on this site each answer one question: tint a color, shade it, blend an overlay, check a pair. A product needs a palette: ten steps of a brand color, each with a text color that passes, in every state, on every surface. The Accessible Palette Workbook does that job in order. Part 1 measures contrast properly (relative luminance, and the right threshold for body text, large text and UI parts, never rounded up). Part 2 builds a ten-step scale of tints and shades, finds the crossover step where white text starts to pass, flattens overlays and hovers before checking them, walks every component state, and ends with a sheet of approved background and text pairs. Worked example: white text on an amber #f59e0b button is 2.14:1, under half of what body text needs; the workbook shows the two honest fixes. WCAG 2.x contrast for screens; not a full accessibility audit or legal advice. Includes a scale worksheet, pair matrix, state checklist, token sheet, a gray reference and three more worked scales. With your purchase comes a personalised sheet: your brand color's own ten-step scale, checked.
