Yeah, real life. Seriously, though, it's a mixture of artist interpretation and just how things look. You don't need to have a list of what colors stones are, do you? Why do you need it for their spec? Just look at some ref, and play around with it until it looks how you want it to.
agree with per and i also want to add, aside from theory, nothing works better than just using your eyes. One of the first things you learn when drawing is to stop drawing from memory and use your eyes and learn to draw what you see. The same should go for textures, materials, shaders etc... if you create your spec in the…
[ QUOTE ] Vig, you keep saying defuse when you mean diffuse. Unless you have explosive textures that you need to disarm? [/ QUOTE ]My Co-Workers: "BOOM! Hahaha Vig mixed up the green and red channels again didn't he? I keep telling him clip the red but he never listens..." Such a bad habit to break. I don't know what it is…
[ QUOTE ] Skin is a unique case more because we pay extra attention to it, so we adjust the specular color to bluish/greenish so the highlight doesn't look yellowish, as explained above. [/ QUOTE ] It's another deal completely why people use a color spec map for skin. If you want one color of blue spec just use a B/W spec…
I doubt that place exists. Normally spec maps are created just like the defuse texture and are very much customized and specific to the object they are applied to. If you're looking to explore specular colors and need a point of reference the best advice I can offer is test test test and test some more and look at other…
in real life there's no specular. Smooth objects reflect more light in the same direction than rough objects. a layer of water on top of a rough object tends to make the surface more smooth and so it reflects light more readily when its wet. Specular is a quick way of simulating that reflection in computer world. So…
Per: In a thread asking about specific or general specular colors for specific and general materials, I think something incorrect like plastic specular color being the same as it's diffuse color, when plastic specular should be white, needed to be pointed out. What you said is more true of metallic items. Incorrect…
"It's another deal completely why people use a color spec map for skin." Not really, but I probably should have explained about the other attributes of a skin's specular map (intensity and the differences at certain areas) rather than a pretty general statement that lacked the proper qualifiers and explanation/correlary.…

And a photo of orange with orange specular and orange with white specular. I'll let you decide what looks more like plastic. Again, it goes down to both knowing what…
