Typography and Design
The Sidley Austin wordmark employs a classic, authoritative serif or refined sans-serif typeface that emphasizes professionalism and institutional credibility. The letterforms are conservative and well-proportioned, reflecting the firm’s long history and established position in the legal market. The typography avoids trendy or overly modern styling, instead projecting the timeless reliability that clients expect from a law firm with over 150 years of experience.
The blue color (#005e85) serves as the primary brand identifier across all firm communications, from letterhead and signage to digital properties and marketing materials.
