LED Aydınlatmanın Farklı Korelasyonlu Renk Sıcaklığındaki Renk Algısının Değerlendirilmesi

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

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.
