This is driving me nutty! I have tried editing the tub rim using both the "colonial combo-clean" and the "colonial bathtub". I select "rim" and no image choice comes up. What do I need to do in order to add another colonial tub rim color?

The tub that contains the rim is the should be the colonial bathtub that doesn't have a shower curtain. I have one in the beta downloads section that has the tub and rim recolored. I can't recall the name of the tub, but the picture should help you find it. I haven't tried a rim recolor with OW, since the last one I did was before OW. But, that is where you should be able to find it.

Thanks, I'll try it once again...lol All I'm seeing is "material override" or whatever it is. People are making them but I don't see HOW! hehe

That's because some objects parts are recolourable, but are textureless: to recolour them you have to alter the parameters in the Material Definition, and you only can have solid colours.
It's an advanced recolouring tecnique; you can read about it here:

the colonial tub used to have a texture file for the rim...I'm not sure with what version though
