Until recently I thought that rainbow They were something children and preferred not to use them in decoration so as not to end an environment recharged by the excess of color. However, the post that Minue made on the spiral stairs and the image you have on these lines have made me rethink my initial opinion.
In the bedroom you see you can see how they used a rainbow as headboard of the bed, which looks like a futon. When combined with white sheets, it has been very original and gives us an idea of how children's bedrooms should be. They have also played with decoration painting eyes on pillows and have put on a pink T-shirt as a tongue.
Let's use the decoration to play or not, the truth is that this headboard looks great because the owners of this room have not tried to fill it with color and they leave all the prominence to the rainbow. If they had put more tones, maybe they would end up getting tired of the bedroom, but as it is, I see it as perfect.
