Claim:
A color sheet having a light-shielding effect, comprising at least a reflecting layer and a color layer such that the color layer is exposed to light from the reflecting layer, wherein: the reflecting layer has a solar-radiation reflectance of 60% or more in a wavelength range of 780 nm to 1350 nm; the color layer has a light transmittance of 30% or more in a wavelength range of 780 nm to 1350 nm and a solar-radiation absorbance of 10 to 80% in a wavelength range of 380 nm to 780 nm; the reflecting layer is made of a polyvinyl chloride type resin compounded with a titanium oxide type white pigment, a plasticizer and at least one material selected from the group consisting of glass beads, hollow glass balloons, and microcapsules; and a hue of the reflecting layer is white or ivory.
