That is not even close to correct. Spherical blob components take a 
vector for the center and a float radius, like the sphere primitive, and 
an additional strength float value. You can also specify a texture for 
individual components. You do not specify a color, but you can specify 
only the pigment of a texture. This is exactly what is specified here.

This warning (not an error) is caused by the fact that the blob shape on 
the whole doesn't have a texture defined. This is usually a mistake, so 
it produces a warning. The components themselves have textures, so it 
will render fine.
