Categorical palettes
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.
Gradients are good for highlighting extremes in a range of values. Use a gradient on single category visualizations only if needed. Multiple gradients are often inaccessible and are discouraged in our system. Gradients should not be used to represent any meaningful progression or divergence. Never use a gradient in place of a sequential palette.
For the full list of approved gradient options, see the IBM Design Language Color page.
