What is the role of color in data visualization and how should it be used?

[Guest]

Data visualization consultant, color plays a vital role in making data visualizations intuitive and engaging, but it should be used thoughtfully. Use contrasting colors to differentiate between categories and emphasize key data points, but avoid overwhelming the viewer with too many bright or conflicting hues. Stick to a consistent color palette and ensure accessibility by considering colorblind-friendly options. Colors should have a clear, intentional purpose, such as drawing attention to trends, outliers, or changes over time. Misusing colors can confuse viewers and reduce the effectiveness of the visualization.
