Colour Palette Builder
Design tool
Build a cohesive colour palette from your corporate colours for slides, reports, charts, and documents.
How it works
Enter a primary colour and, if available, a secondary colour. The tool generates matching accent colours, background colours, text colours, RGB values, CMYK values, and a simple slide preview. You can start from a preset, adjust the mood, click any swatch to copy the hex code, and print or save the result as a PDF. Data stays on your device and is not sent to a server.
When to use it
- Best used for: Building a practical colour palette for presentations, reports, charts, handouts, and public-facing documents.
- Not used for: Replacing formal brand standards, accessibility review, graphic design advice, or professional print production checks.
- Audience: Planners, local governments, consultants, students, non-profits, small organizations, and anyone preparing clear visual materials.
Notes and limits
- Assumption: The entered colours are valid corporate or project colours and can be used as the starting point for a broader palette.
- Known constraint: Generated colours may not meet every branding, accessibility, or print-production requirement.
- Edge case: Very dark, very light, or highly saturated colours may produce accent colours that need manual adjustment before use.
