Abstract: Under various light sources, the color of dyed fabrics could be observed in different ways. In this study, the red (R), green (G) and blue (B) dyed fabrics were evaluated through color difference (ΔE) and illuminance difference (ΔI) under daylight (D65), fluorescence (F, TL84, CWF), and ultraviolet (UV) lights. It was found that when D65, a standard daylight illuminant, is used as the reference, ΔE value under TL84 and CWF light sources was not significantly different. Therefore, D65 can be complemented by TL84 and CWF for color evaluation to enhance accuracy. The study also highlighted that using a 45-degree viewing angle yielded the most objective color evaluation results. This angle provides optimal conditions for observing light reflection, contributing to more reliable color evaluation. Additionally, dye concentration had a significant impact on color evaluation. An incorrect dye concentration can alter the ability of fabric to absorb light, leading to inaccurate evaluations. Furthermore, washing cycles also affect the colorfastness of dyed fabrics, with increased washing leading to a brighter appearance and higher light reflection.
