What Color Is Harbor Side Blue, Really?
Harbor Side Blue reads as a cool blue-green tone — mid-tone — versatile but shifts visibly with light. The notes below cover how Benjamin Moore 740 behaves in different light and the closest matches at competing US brands.
Best Rooms and Uses for Harbor Side Blue
Harbor Side Blue is versatile enough for full rooms but has enough depth to anchor a space, so it suits living rooms, bedrooms and cabinetry alike. Teals add character without shouting — good for a vanity, an island or a feature wall.
How Lighting Changes Harbor Side Blue
Harbor Side Blue sits in the mid-range at LRV 39, so it shifts visibly through the day — lighter and more open in morning light, deeper and moodier after dark. Its teal 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. South-facing rooms will pull it lighter and warmer, while north light cools it down.
Most complaints about Harbor Side Blue are a light mismatch. Upload a photo of your actual room and see it on your walls — then ask for the same wall in north light or evening lamps before you buy a single sample.
