Yes, that solved the problem. Many thanks, you both!
I'm posting the code, for reference.
osg::ref_ptr<osg::StateSet> stateSet(root->getOrCreateStateSet());
osg::Image* image = new osg::Image;
// allocate the image data, noPixels x 1 x 1 with 4 rgba floats -
equivilant to a Vec4!
int noPixels = 1;
image->allocateImage(noPixels,1,1,GL_RGBA,GL_FLOAT);
image->setInternalTextureFormat(GL_RGBA);
// fill in the image data.
osg::Vec4* dataPtr = (osg::Vec4*)image->data();
osg::Vec4 color(1,1,1,1);
*dataPtr = color;
// make fake texture
osg::Texture2D* fakeTex = new osg::Texture2D;
fakeTex->setWrap(osg::Texture2D::WRAP_S,osg::Texture2D::CLAMP_TO_EDGE);
fakeTex->setWrap(osg::Texture2D::WRAP_T,osg::Texture2D::CLAMP_TO_EDGE);
fakeTex->setFilter(osg::Texture2D::MIN_FILTER,osg::Texture2D::LINEAR);
fakeTex->setFilter(osg::Texture2D::MAG_FILTER,osg::Texture2D::LINEAR);
fakeTex->setImage(image);
// add fake texture
stateSet->setTextureAttribute(0,fakeTex,osg::StateAttribute::ON);
stateSet->setTextureMode(0,GL_TEXTURE_1D,osg::StateAttribute::OFF);
stateSet->setTextureMode(0,GL_TEXTURE_2D,osg::StateAttribute::ON);
stateSet->setTextureMode(0,GL_TEXTURE_3D,osg::StateAttribute::OFF);
