The rarely used service rooms (e.g. laundry, pantry, toilet) should also be decoratively furnished, as they are equally part of our home, even if practicality is their main criteria

Vermilion (alias Chinese red) is a brilliant orage-red hue. It dominates the space, so use it very carefully in interior design. It is recommended as a color for accessories if you want to throw up space or creating a focal point is the target. It should be used on large surface in a room which we stay only a little, but not for sleeping (e.g. separate dining room). The pigment was made from mineral cinnabar (mercury sulfid) which is toxic, so it is now produced artificially.
