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.
