Can live flowers (as opposed to white coronations in vases) absorb dyes? If so, which flowers and dyes will work?

There is a lot of information online about colouring flowers once cut, but not so much on this!
I'm working on a project on an industrial lot where wastewater containing dyes is diverted to a shored up 'pond'--a very blue pond. If we plant flowers around this pond where they will draw water from it, are they likely to absorb the blue dye, and if so, be harmed by it? What flowers would most readily absorb the colour? This is in NSW Australia, and the dye is of the kind used to colour fibreboard-like materials (to indicate that they are water-resistant and so on).
