Teal is a versatile color. Set between blue and green on the color wheel, true teal most closely resembles cyan blue with a green tint. Appropriate for any room of the house, teal can be used successfully as a main color, complementary color or accent color. There are several teal decorating ideas. You can use teal decorating ideas to make your ocean-themed living room come together. Paint one large accent wall in your living room dark teal, and leave the other walls and ceiling white. Adorn the teal wall with framed ocean pictures and shelves filled with ocean treasures like starfish, bottles filled with sand, rocks and large seashells. Hang up other ocean decor items on other walls, but make your teal wall the main focal point of the room by putting the most decorative accents in this area.
