Choose light reflective value numbers that suit room purpose, then test swatches in corners, not just near windows. Off-whites with subtle undertones maintain warmth while multiplying brightness. Satin or matte-scrubbable finishes tame glare on large planes. Paint ceilings a whisper lighter than walls, extend color into alcoves, and notice how shadows retreat, revealing architecture that felt lost yesterday.
Mirrors opposite or adjacent to skylight fall lines double perceived depth, but scale matters. Narrow vertical mirrors elongate hallways, while low, wide pieces spread table-height sparkle. Brushed metallic accents, satin metals, and glass tile catch light softly. Avoid excessive gloss near screens and bedtime areas. Curate reflections intentionally, steering brightness toward working surfaces and away from frequent resting gazes.
