Curtain with cushions and pillows
Using complementary colours rather than the similar colours can be another good choice.

Many choose curtain colours matching with cushions and pillows of the room. The main thing is to consider the fabrics of the cushions or pillows.
Using the same fabric for cushions and curtains is a simple but beautiful choice. Considering the shades can add a bit of specialty here. Change in the patterns of the fabrics, considering the position of the cushions and curtains may bring a good look in the room.
Using complementary colours rather than the similar colours can be another good choice. It can be contrastive also. One can choose solid colours or printed fabrics for both cushions and curtains in that case.
Beside this one can easily think of coordinating it with another element in the room. Colour of upholstery or any other particular thing in the room can contribute in this regard. All you have to do is just choose a particular element in the room, comparing that with the wall colour and other things, you can easily match three of this.
Choosing colourful pillows with neutral fabric colours for curtain like white, off-white, black, grey is an easiest way to match and bring an eye-catchy look in the room.
Throw pillows are one of the ways to inject style into your living room, family room, study-room and bedroom.
There are so abundance of affordable, beautiful pillows out there, without using just two or three solid-coloured pillows, would ruin the beauty of a fine-looking curtain set. Hence, whatever colour you choose, keep the other elements i.e. pillows, wall colour etc of the house in mind.
