description: Using the well known CIELAB colour space parameters: lightness (L*), redness (a*), yellowness (b*), chroma (C*) and hue angle (h°) relative to the standard illuminants D65 (natural day light), A (tungsten light), and the standard 10° observer, the colour expression of two new symmetrical direct disazo-stilbene dyes was performed. The colour differences AEab* and AECMC were calculated against one standard, indicating a high colouring power of the both disazo-stilbene dyes. The studied dyes were synthesized using 4,4'- diaminostilbene-2,2'-disulphonic acid as middle eco-friendly component and 2-methyl-Nacetoacetanilide and 5-acetoacetylaminobenzimidazolone as coupling components respectively.
