I would say so.

I think that ImageClearColor (not ImageClearColour :-)) should 
generate an object.  This would be the kind of object that appears 
only fleetingly during 3DMF reading, like the Caps object 
(kQ3ObjectTypeGeometryCaps).  If you look at 
E3Read_3DMF_Geom_Cylinder, for instance, it calls Q3File_ReadObject 
to get child objects, and if the child is of type 
kQ3ObjectTypeGeometryCaps, it extracts the caps flag, puts the caps 
flag in the cylinder data, and disposes the caps object.

You'd register ImageClearColor as a class, and its read method would, 
I suppose, use Q3Float32_Read to read the components of the color.
