A sofa is often the most expensive piece of furniture in the room, and once you have made the investment, you must design around that key piece. Finding the right curtain colour to match a green sofa is dependent on the actual shade of the sofa and then staying within that colour family to create a polished look in the room.
A hunter green sofa has perhaps the most options for matching the curtain colour. When you look at a design colour wheel, you'll see that directly opposite the colour green is the colour red. Just as hunter green is a dilution of true green, you'll want to go with a dilution of true red for the curtain colour. A good example of this would be burgundy, a colour commonly paired with hunter green. For a different look, you can go with an accent colour such as ivory or white. Hunter green is a versatile shade that can go with either cool or warm tones.
Sage green is a very light dilution of true green in the colour wheel. It has more brown and yellow tones than blue, which gives you an idea of what colours to match with it. Light beige or light yellow are colours that are within this same colour family, and they will match well with a sofa in this shade. Unlike other greens, sage is commonly associated with warmer colours and can be paired with ivory instead of plain white. Going back to the colour wheel, rust red would be directly opposite this dilution of green and would make for a striking complementary colour.
Bold Green Colors
A bold or a true green can be matched with several different colours. This green is best when paired with cool colours rather than neutral. For example, bright turquoise or bright, crisp white can be paired with true green. Navy is another colour that is commonly used with green. Another option is to go with a bold white and black curtain design to give the room a more modern edge.
Pastel Green Colors
Colour matching pastel greens will depend largely on what colours are mixed with the green. For example, if the shade of green is a light celery colour, pairing it with neutral coloured curtains would complement the sofa. If the shade is more of a crisp pastel green, stick with white or a cool colour combination to match it, such as a pastel blue.
