Color has a semantic content which touching directly our sentimental world. It has a significant influence on the aesthetic properties of textiles. Color is the result of dyeing a textile material depends on the chemical structure of the dyes and the physical and chemical properties. Manufacturers are expected to provide their material with a high level of quality in color so that it meets the needs of its customers. Role of illuminant and depth of shade on CIELAB color spaces were evaluated by Datacolor 650 (reflectance spectrophotometer) to get the difference in color spaces (DL*, Da*, Db*, DC* and DH*) of reactive dyed fabric focused on this paper. The color spaces of dyed fabrics shows higher lightness at higher concentration usually expressed by DL*. Correlated color temperature of illuminant is maximum for D65 (6500K). Fabrics became darker when the colorant concentrations increased as well as illuminants CCT. Samples showed evidence of more redness and yellowness than the standard. Saturation level of dye also influenced positively in most cases i.e more intensive in higher dye concentration and fabric GSM.

Keywords: Correlated color temperature, Color spaces, Color Build-up, Illuminant, Shade depth, Reactive dye.
