 Table [commonMatReflectance] describes acceptable Fresnel reflectance values for various types of materials (no real world material has a value under 2%).

 Table [fNormalMetals] lists the $\fNormal$ values for a few metals. The values are given in sRGB and must be used as the base color in our material model. Please refer to the annex, section [Specular color], for an explanation of how these sRGB colors are computed from measured data.
