Question

With OpenSceneGraph, how do I make it use GL_REPLACE to render my texture? I do not want the color of my texture to change with orientation. I also want the rendered color to match the values of the texture.

On the Geode that contains the texture (and probably any node above it, as long as you don't override it), you can do this:

osg::TexEnv* pTexEnv = new osg::TexEnv();
pTexEnv->setMode(osg::TexEnv::REPLACE);
pGeode->getOrCreateStateSet()->setTextureAttributeAndModes(0, pTexEnv, osg::StateAttribute::ON);

Now the texture will be drawn with exactly it's own color.
