With increasing interest in improving indoor lighting comfort and energy efficiency, the development of lightweight and multifunctional decorative materials has become important. In this study, a polyester organza fabric-polyester mesh was fabricated using a direct thermal welding method to adjust an indoor atmosphere. Different colors of organza fabric and polyester mesh were welded under various temperatures ranging from 320 to 480 °C, and their mechanical strength, visible light transmittance, and color rendering were analyzed. Brighter organza colors exhibited higher visible light transmittances, while these values decreased with multi-stacking of organza fabrics. The combination of different colors of organza fabrics produced forty-eight novel colors. Increasing welding temperature enhanced polymer chain entanglement between organza fabric and polyester mesh, achieving a maximum joint strength of 10.25 MPa. The direct welding of organza fabric and polyester mesh is lightweight, flexible, and enables color diversity, therefore it can be a good candidate material for lighting and shading to adjust indoor atmosphere.
