Yes, look under Fundamentals in the Help and look under Pen for more information. The color values are entered in values from 0(0) to 1(255). For your example divide 183 by 255. Color value in table.pnt will be 1.00000 0.71765 0.00000. Here is an example from my table.pnt file.
pen 1 thickness 0.020 in color 0.23529 0.21961 1.00000 prints geometry in blue
If you have more than one custom color you are trying to print here are some other things to try. Try removing the color and thickness values in the table.pnt file. ProE will use the colors and thicknesses from the drawing file for printing. User defined colors print using pen 1.
