Not a chemist.  If Juanse wants to do it at beekeeper level I doubt it 
would be feasible as you would need pressure filtering.  It is probable 
that using some sort of flocculation would work, i.e. adding something 
as you suggested, diatomaceus earth or charcoal etc..

Dussek Campbell when they were operating, maintained they were able to 
remove the colour just by forcing through a succession of smaller and 
smaller screens.  However on a chance meeting I asked the bloke who 
actually did the job.  He allowed there was some chemical process involved .
