Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Sigh of Relief reflects noticeably more light off the walls, making the space read more open than Thames Fog.

Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Sigh of Relief returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
