If the color is brown (shades range from tan to chocolate) then it is most likely a phenolic laminate like XPC or FR2. These types of PCB laminate are most often used in high volume, low cost consumer products (i.e. VCR's, TV's). Last time I looked (many years ago) Radio Shack Catalog #: 276-1499 is a tan colored phenolic 2-Sided Copper-Clad PC Board. If the color is green, blue, red or, orange then it is most likely normal FR4 (the translucent material) with one or more solid copper internal planes and a colored solder mask (i.e. PC motherboard, PCI card). IMHO, FR4 is best mechanically and electrically, XPC and FR2 are only used where lower cost in volume is needed (phenolic PCB's are often punched instead of drilled/routed). Here's a couple links with some good info.
