The following chart provides Diffuse and Reflection Color values that help you create realistic metallic shaders with V-Ray for Maya: Name Base (diffuse) color Reflection color Metalness Base color (web) Red Green Blue Red Green Blue Silver 252 251 250 255 255 255 1 fefefd Gold 244 202 104 255 250 195 1 fbe6ab Copper 238 159 137 254 231 216 1 f8cfc2 Aluminium 231 233 235 245 250 252 1 f5f6f6 Chromium 142 141 141 145 142 176 1 c5c5c5 Lead 168 169 176 191 192 209 1 d4d5d9 Platinum 244 238 216 254 253 249 1 faf8ee Titanium 246 240 209 254 254 250 1 fcf9ea Tungsten 236 213 193 251 241 218 1 f7ece2 Iron 227 224 211 242 245 244 1 f3f1eb Vanadium 242 228 199 254 251 242 1 faf3e5 Zinc 223 222 218 245 247 249 1 f1f0ef Nickel 227 220 193 245 245 237 1 f3efe2 Mercury 199 199 199 224 232 240 1 e5e5e5 Cobalt 175 168 158 205 205 208 1 d8d4cf The Index of Refraction (IOR) plays an important role when creating a physically based material and has to be considered as part of the shader. For metallic materials (having Metalness value of 1) it is automatically calculated from the Diffuse and Reflection colors: see the  Artist Friendly Metallic Fresnel  paper. For materials with Metalness < 1, the Fresnel IOR parameter from the interface is taken into account. The site  RefractiveIndex.info  is a great resource for understanding the proper IOR of different materials. Note that in versions before V-Ray 6, update 1 the Fresnel IOR still plays a role for creating physically accurate metallic shaders even if the Metalness is set to 1. For detailed information on the Metalness parameter, go to  Understanding Metalness  Chaos blog post.  Useful information on metallic surfaces can be found at the  Journal of Computer Graphics Techniques  site.
