Carlos, if you look at a phenolic riser under strong light you can see what looks to be "grain" to it. It's actually just layers of paper which are compressed and impregnated with a resin. I've seen some that were faded to a degree by U.V. exposure that were almost a grey color. If you look at one that the Bowdoc or Rich has restored, they look as black as a Brunswick bowling ball. Hope you are doing ok, CKruse
