Limit your palette

Using too many colours cause the message to get lost. It can also cause overwhelm and confuse your users.

To communicate clearly, limit the number of colours you use in your design to 3-colours.

Divide colour usage according to the 60-30-10 rule.

• The primary colour should dominate 60% of your visualisation,
• 30% should be dedicated to the secondary colour
• 10% is an accent colour that will highlight important information.

If you need more contrast, consider using shades of the colours you already have.
