Deep blue and green colors usually go well with teak furniture. Teak wood generally has brown undertones, which are often complemented by blues and greens.
To match furniture colors with cushions and upholstery, the first step is to select a complementary color. Complementary colors are directly across from each other on a color wheel. For example, blue and orange are complementary.
The natural hue of teak wood is close to red and orange on a color wheel. Therefore, colors close to blue and green suit it best.
Shades of the same type of wood can vary within a set color range, so it is helpful to identify the color undertones of an individual furniture piece. If the teak is more of a reddish brown, green upholstery and fabrics should suit it best. Likewise, if the teak is more orange, it is better suited to blue fabrics. An especially light teak may even have yellow undertones that go well with purples.
Neutral tones such as beige and tan go with most types of wood. If bright colors are not desired, or if the room is too dark, light beige, tan or even cream-colored upholstery and cushions can also match the teak furniture.
