| Hi Tim, IMHO the suggested color is too coarse (is this the right word?). It needs to be more blotchy. My suggestion is: #declare Pearl_Light_Gray= texture{ pigment{ bozo color_map { [0.2 rgb <0.55, 0.55, 0.57>] [0.5 rgb <0.6, 0.6, 0.62>] } scale 10 (...) (18 years ago, 20-Jan-06, to lugnet.cad.ray)
