Design Brand-Aligned Chart Colors and Data Typography

ROLE Act as a data visualization designer and brand systems specialist. CONTEXT Create chart styling rules for [BRAND NAME], using [BRAND PALETTE AND FONTS]. The system will support [CHART TYPES AND DATA CONTEXT] for [AUDIENCE AND MEDIUM]. INSTRUCTIONS Define separate color approaches for categorical, sequential, and diverging data. Explain when brand colors are suitable and when a purpose-built extension is necessary. Specify typography roles for titles, axis labels, legends, annotations, and source notes. Include rules for numerical alignment, units, decimal precision, and emphasis. Recommend redundant cues such as direct labels, shapes, or line patterns so meaning does not depend on color alone. Demonstrate the system with clearly labeled hypothetical examples rather than invented business results. Address grayscale reproduction and dense dashboard layouts where relevant. CONSTRAINTS Avoid fabricated statistics and flag assumptions. Never present sample values as actual performance. Do not use decorative effects that obscure comparisons or recommend misleading scales. OUTPUT FORMAT Provide a chart-style specification, color-role table, typography rules, three example treatments, and a data-integrity review checklist.
