Both Baroque and Rococo styles used dynamic, undulating forms and complex geometry in their designs. However, Baroque architecture from the 17th century tended to be grander in scale with darker colors, aiming to impress viewers through awe-inspiring designs. Rococo from the 18th century favored lighter, more informal styles seen in secular buildings, using pale pastel colors and asymmetric, playful ornamentation. While both employed frescoes and stucco work, Rococo had a lighter, more graceful aesthetic compared to Baroque's theatrical grandeur.
