The fact that shape and colour can strongly influence human emotions has long been well-known. Now this knowledge has been adopted by clothing and interior designers, who use scientific psychotextiles in everyday life. These are knitted fabrics with purpose-made electrochromic composite yarns. They can literally be programmed to change colour and pattern to directly affect a person's mood - create a party atmosphere, or, conversely, a tranquil one. It is becoming a kind of "visual medicine," an alternative to antidepressants.
Psychotextiles’ ‘behaviour’ can be adjusted to almost any event - a change in weather, a change of seasons and time of day, etc. Distinct stylistic directions associated with these technological possibilities are appearing in art, design and architecture.
