In the middle ages, the emphasis was more on the decoration of public utility buildings. The styles used were elaborate and magnificent to give it the perfect royal touch. Italian designs are still very popular for their imperial looks.
Spanish interior decorating is famous for its rich colors. On the other hand, France was a leader in setting innovative styles that changed with every monarch. While choosing colors, interior decorators must also consider the intensity of the light source in a room. It is always better to do a test patch on a wall before deciding on a type of paint and color. Some colors and shades look completely different in varying paint finishes.
If you’re influenced by a certain look, try and contact the designer who took up the original job. There are many who do the job well but at the end you may not get just what you want because your designer may not have understood what you really want.
