Colours and contrast checks
Set the background, question, answer, button, accent and error colours, with a warning when text would be hard to read.
Every plan
Colours in the Design tab has seven: Background, Questions, Answers, Buttons, Button text, Accent and Error. Click a swatch to pick a colour or paste a hex value.
Contrast checks
FormsAI checks the pairs people read: question text on the background, answer text on the background, the button on the background and button text on the button. When a pair is too faint, a warning under the colour gives the ratio and the minimum needed: 4.5:1 for text and 3:1 for the button against the background. When everything passes you'll see All text meets WCAG AA contrast.
To change colours on just one screen, see style one screen differently.
