About PPG / Glidden Quaking Grass
At LRV 54, Quaking Grass is a light color that bounces daylight around a room without tipping into stark white. Its green undertone is the part to watch: it gets picked up by whatever sits next to it, so test it against your trim, floor and the room's main light before committing. It holds its undertone in most exposures, which is what makes light shades like this so forgiving room to room.
Quaking Grass is an easy whole-room color for living spaces and bedrooms, and light enough to carry onto trim or a ceiling if you want a soft, seamless look. Greens bridge indoors and out, so they suit living rooms, kitchens and sunrooms.
