In the below example, current data visualization colors failed to meet a 3:1 color contrast ratio against their background, posing accessibility challenges for users with varying visual abilities.
The existing sequential color palette lacks sufficient contrast, as demonstrated in the example below. With multiple similar shades of blue, it becomes challenging for users to differentiate between different data points.
The current design system lacks comprehensive documentation and guidelines for color usage, creating inconsistencies and ambiguity in color selection and application across various data visualization contexts.
