This document provides five design secrets for creating less overwhelming interfaces: 1) Use neutral base colors and strong accent colors with restraint and balance. 2) Create a strong anchor through placement, contrast, and indicating what users should focus on. 3) Vary box styles, create horizontal terraces, and reduce visual noise to "de-boxify". 4) Ensure consistent spacing, margins, and styles to "sweat the details". 5) Any combination of these secrets can be used to improve interface design outcomes.
