Once this color is chosen, there are several possibilities:
Declining this color by opting for a décor in a shadow: Stop your choice for example on a blue curtain and decide an associated decoration in tones of more sustained or clearer blues associated with beige, sand and gray.
Advantage: No false note, an elegant and timeless interior that will delight lovers of natural and classic atmospheres.

Adopt contrasting decoration by matching this color with its complementary.
The complementary colors are those that are opposite in the chromatic circle: red and green, orange and blue, yellow and purple.

For example stop your choice on a blue curtain and wake up your interior by combining cushions in orange gradients.
Advantage: A bright and dynamized interior that will carry the adhesion of amateurs of design and nomadic atmosphere.

Focus on colorful decoration without being high in color by combining your base color with an associated color.
The associated colors are those located side by side in the chromatic circle.
Choose for example a blue curtain and harmonize your interior by choosing colors in purple and raspberry pink tones.
Advantage: An interior while in harmony and sweetness that will seduce serene ambience lovers.

Golden Rule: For successful decoration, never choose more than 4 different colors: play rather on tone gradients.
