When the clothes get wet, the cloth will have darker colors. Wet clothes are darker than dry because wet cloth so there is less light reflection, dry cloth. Seeing that there are darker colored fabrics, wet cloth to dry multiple concepts describe about this phenomenon. But there is still no information to confirm the theory that credible and clear enough. Group has studied and created reproductions of the fabric and the fabric dry while saetngonuphak while wet RGB color values as well as the different color of cloth wet with solution of different concentration. By a R G B value from education coordinates and intensity of rangsisathon. The various colours of the transmitted radiation wet with solvents that have a different refractive index. When the clothes found at the microscope magnification endoscopy 40X to wet cloth is inserted into the liquid molecules in space of RGB values with wet cloth and fabric that RGB values of changed from a dry cloth. Use the Lux meter measurements of light intensity transmission and radiation rangsisathon. When drops of solution refractive index 1.33, 1.36, 1.54, 1.40 1.46, and controls, respectively. Found that the fabric that drops with solvents that have a refractive index 1.54 most is that most color intensity. Refraction index more of the light intensity increase rangsisathon and the better the transmission is reduced, so we see the darker colored fabrics.
