Layer LED accent lighting in living rooms by first establishing a warm ambient base light at two thousand seven hundred to three thousand kelvin set between ten and twenty percent brightness. Add dimmable accent lights focused on key areas, such as collectibles or architectural features, using high-CRI flicker-free LEDs angled around thirty degrees. Incorporate subtle colored RGB lights at low levels for mood without overwhelming. This layering approach balances warmth, color accuracy, and visual comfort, transforming your living room into a cozy, stylish space without causing eye strain or visual fatigue.
