Abstract

Renk
ve ışık, iç mimarlık alanında tasarımın temel unsuru olan ayrılmaz nesnelerdir.
Işık değiştiğinde, algılanan iç mekânın yüzey renk görünümü de değişir. Renk
algısındaki bu değişim, yalnızca bir ışık kaynağı türüne veya aydınlatma
yoğunluğuna değil, aynı zamanda bir ışık kaynağının renk sıcaklığına da
bağlıdır. Bu çalışmanın amacı, LED aydınlatmanın farklı renk sıcaklığındaki
renk algısını nasıl etkilediğini anlamaktır. LED aydınlatmanın iki farklı sıcak
(2700º K) ve soğuk (4000º K) renk sıcaklığı altında asıl renkler ile algılanan
renk eğilimlerini karşılaştırmak amacıyla bir çalışma yürütülmüştür. Bu
çalışmada, asıl renkler ile algılanan renkler arasındaki olası eğilimleri ve
kalıpları ortaya çıkarmak için Doğal Renk Sistemi (NCS), bir renk notasyon
sistemi olarak kullanılmıştır. LED aydınlatmanın her iki 2700º K ve 4000º K
renk sıcaklığı altında algılanan renkler için genel eğilimlerde, her bir asıl
renk için nüans (rengin değeri ve doygunluğu) renk alanında benzer desenleri
ortaya çıkarmış ve renk türü renk alanında dağılma göstermiştir.

Evaluation of Color Perception in Different Correlated Color Temperature of LED Lighting

Abstract

Color and light are inseparable entities that
are the essential design factors in the field of interior architecture. When
the light changes, the perceived color appearance of a surface within an
interior environment also changes. The change in color perception is not only
related to the type of a light source or the intensity of illumination, but
also to the correlated color temperature (CCT) of a light source. The aim of
this study is to understand how different CCTs of light-emitting diode (LED)
lighting influence the color perception. A study is conducted to compare the
perceptive color tendencies for inherent colors under two different CCTs of LED
lighting, i.e. warm (2700º K) and cool (4000º K). In the study, Natural Color
System (NCS) is utilized as a color notation system to reveal the possible
tendencies and patterns concerning the relationship between the inherent and
perceived colors. The general tendencies for the perceived colors revealed
similar patterns in the nuance (i.e. blackness and chromaticness) color area
for each inherent color and showed dispersion on the hue color area under the
CCTs of both 2700º K and 4000º K LED lighting.
