Color Scheme
Steel Blue
A steel-blue palette that combines credibility, precision, and calm. Useful for analysis-heavy decks.
Content color references (ColorRef)
Swatches above are the hex catalog values for this scheme. In OPF documents, content can also reference those slots by name (for example accent1, textSecondary) or define deck-level variables and use var:<id> in rich text and styled table cells. The OPF Config below demonstrates named runs today; variables and styled-cell ColorRef appear in the snippet once the gallery pins @openpresentation/opf 0.11.x (reference layer, Format card). Bundle portable decks with the opf bundle CLI after publishing.

Best Use Cases
Research reports, operating reviews, healthcare decks, insurance presentations
Color Psychology
Blue-gray tones feel precise and measured, making technical or analytical content easier to trust.
Accessibility
WCAG AAAThe default dark1/light1 pairing is 21:1, exceeding WCAG AAA for normal text. Check accent usage against the chosen background for small labels.

Industry Fit
General Color Tips
60-30-10 Rule
Use your primary color 60% of the time, secondary 30%, and accent 10% for visual balance.
WCAG AA Minimum
Ensure text has at least 4.5:1 contrast ratio against backgrounds. All schemes in this catalog meet WCAG AA.
Industry Context Matters
Match color psychology to audience expectations. Blue works for finance, green works for health, and purple works for technology.
Test on Projectors
Colors shift on projectors. Test dark backgrounds in the actual presentation environment before presenting.
