Are any weed/grass killers same color as miracle grow fertilizer?

Question

I know, stupid question but I bought a house and sellers left a nice dial- spray bottle half full of blue or bluish green liquid.
It looks exactly like Miracle Grow fertilizer, but am afraid to use it in case it’s actually a weed/grass killer!
I hate to waste it.
Does anyone know if any weed/grass killer is same color as Miracle Grow fertilizer?
Thanks!

There is no telling what it is, plus you don't know how old it is. Pesticides are only good for a couple of years.

Safest thing to do would be to properly dispose of it.
