Questions
- How many colours should a presentation use?
- Most decks need a background, a surface for cards, a text colour, a muted text colour and one or two accents. Fewer colours used consistently look more polished than many.
- What contrast do slide colours need?
- This tool follows WCAG contrast ratios: body text at least 7:1 against the background, muted text at least 4.5:1, and accents at least 3:1, the bar for large text and graphics. Projectors wash colours out, so extra contrast helps.
- Light or dark slides?
- Light slides tend to hold up better in bright rooms and printed handouts. Dark slides look striking on screens and in dim rooms. Generate both and compare the previews.
- How do I use the palette in PowerPoint or Google Slides?
- Copy the hex codes, then set them as custom theme colours: in PowerPoint under Design, Variants, Colors, Customize Colors, and in Google Slides under Slide, Edit theme, Colors.
