This study was conducted in order to understand the effects of color(light) environment of art therapy
space on Nurie coloring and emotional change, as a first step for understanding the impact of color(light)
environment of art therapy space on client's emotion. The color(light) environment of art therapy space was
changed by using LED lightings which have different correlated color temperatures(CCT) of 7500K or 2900K.
Emotional assessment and Nurie coloring were conducted for 50 number of university students by using
emotional evaluation questionnaire proposed by Soon-Duk Jee(2007) and Aura Nurie by Suenaga Tamio,
respectively, and the results were analyzed using a SPSS19.0. The results showed that the color(light)
environment having CCT of 2900K caused emotions such as 'sentiment', 'relaxing', 'dignity', 'warm', and
'soft'. Meanwhile, the color(light) environment having CCT of 6500K caused emotions such as 'dynamic',
'clear', 'refreshing', 'vivid', and 'cool'. Futhermore, main colors of Nurie coloring, conducted under the
different color(light) environment having CCT of 6500K, were analyzed as warm colors which are related to
'psychology with extroverted tendency' in color chart of 'Heart & Color'. However, main colors of Nurie
coloring, conducted under the different color(light) environment having CCT of 2900K, were analyzed as
cold colors which are related to 'psychology with introverted tendency' in color chart. In conclusion, the
color(light) environment of art therapy space have significant impacts on the main colors of Nurie coloring
and emotional change, which implies that client's emotion can be varied as color(light) environment of art
therapy space changes.
