Discloses is a water-soluble color coating paint for coating a rubber foam thermal insulation material and a method for manufacturing the same, and specifically, a color coating paint and an insulation color coating paint which have excellent adhesion to a porous rubber foam thermal insulation material, and retain elasticity of the thermal insulation material, as well as very improved photocatalytic performance, and a method for manufacturing the same. The color coating paint may be applied to a surface regardless of the material or condition of the surface to be painted, and may be coated to a soft or porous surface due to elasticity provided therein. The coating film produced by the color coating paint blocks 95% or more of the emission of volatile organic compounds from the surface of the foam rubber thermal insulation material into the atmosphere.
