The color palette for data visualizations is a select subset of the IBM Design Language color palette. It is designed to maximize accessibility and harmony within a page.
Categorical (or qualitative) palettes are best when you want to distinguish discrete categories of data that do not have an inherent correlation.
The colors of this palette should be applied in sequence strictly as described below. The sequence is carefully curated to maximize contrast between neighboring colors to help with visual differentiation.
You can override the categorical sequence with one of the following palettes if the exact number of data categories is predictable.
The monochromatic palettes are good for relationship charts and trend charts. In light themes, the darkest color denotes the largest values. In dark themes, the lightest color denotes the largest values.
