Wright (2011) convinces us that we are all affected by colour psychologically, and that every shade affects exact psychological modes, in that way controllingmood and behaviour in the spectator, though such effects are uncontrolledby culture, gender or age and are for that reason unsurprising. Psychologicallyall colours may wellbe classified into one of four groups, where thefour groups pave the way foruniversal colour harmony, and colours from the identical group tendconstantly harmonise, while those from dissimilar groups by no means tend to harmonise. In relation to colour penchant, this psychological theory proposes that the design that humanity too may well be carved up into four psychological groups that match up to the four colour groups. Thefour psychological principal colours are red, blue, yellow and green. Red is very friendly abut aggressive colour; whereas blue is cold unemotional and unfriendly. When it comes to yellow, it is strongest colour psychologically; whereas green is supposed as being too weak and tasteless.
