# Accessibility notes
|
|
|
|
Colour Tools treats colour as data as well as appearance. Swatches are paired
|
|
with textual values, gamut/contrast status uses text and symbols in addition to
|
|
hue, and generated palettes remain usable without visually distinguishing
|
|
every swatch.
|
|
|
|
Workspace navigation uses tabs with selected state and arrow/Home/End keyboard
|
|
navigation. Native inputs and labelled controls are preferred. The large picker
|
|
supports arrow-key adjustment and announces its saturation and brightness;
|
|
image sampling supports numeric coordinates and keyboard movement in addition
|
|
to pointer selection. Calculation and file statuses use live regions without
|
|
clearing the last valid result while a user is typing.
|
|
|
|
The shared Toolbox shell provides system, light and dark themes. Focus rings,
|
|
touch targets, reflow and text contrast should be checked in all themes and at
|
|
400% zoom. A WCAG contrast result is not itself proof that the complete
|
|
interface conforms: test keyboard order, names/roles/values, error recovery,
|
|
high contrast modes, reduced motion and screen-reader output in context.
