kitchen cabinets clearly divided into two distinct materials upper cabinets warm neutral beige low saturation subtle stone like smoothness diffuse reflectance approx 0 60 0 70 soft micro roughness uniform matte behavior lower cabinets and island warm medium wood with golden brown chroma fine vertical grain satin finish reflectance approx 0 35 0 45 controlled gloss with slight anisotropy flooring medium natural oak with soft beige undertones medium contrast grain matte finish diffuse reflectance approx 0 55 0 65 minimal specular response generate calibrated albedo values roughness maps and normal intensity consistent with real world materials maintain strict color fidelity avoid oversaturation and match all tones precisely for interior visualization and material reproduction
