Bold accent colors like lemon yellow and oxblood red complement Universal Khaki beautifully. These hues add vibrancy and focal interest against its warm neutral base. Accent pieces in these colors — such as stools, pendants, or decorative pillows — create contrast without overwhelming the calming atmosphere. Using one confident accent color follows the 60-30-10 design rule, where Universal Khaki dominates, supporting a balanced yet energized room palette.
