What color is better in a sunshade?

When choosing car sunshades, cool colors such as blue, green, and white are better options. These colors can reflect sunlight, reduce heat absorption, and provide a cooler visual and physical experience. In contrast, warm colors like black and red have strong heat absorption properties, which may increase the car interior temperature and are less effective for sun shading and cooling. Additionally, the material of the sunshade is equally important. Sunshades made of aluminum foil or PVC can better reflect light and block heat transfer, and when combined with cool colors, they further improve the sun shading effect. Overall, considering colour, material, and installation method, cool-colored sunshades perform better in sun protection and heat insulation, making them ideal for daily use.
