I'm looking to add some colour to the flames when burning fire rope, the colours I'm looking to produce are Purple, Orange and Green.

Normally I use paraffin but guessing to mix with meths would be a better liquid? Can anyone recommend suitable mixes to achieve the colours?

Alcohols can be made to burn green with boric acid but it's a weak green The usual flame colourants struggle to make colours as they are not soluble in paraffins and if you get any into the flame it's not hot enough to form the colours well.

 

Good strong colours are better done with lances.

I have used Boric acid and meths in tin cans nailed to stakes. It is a weak green and the smell is awful, Definitely to be done in a very well ventilated area. But if you have nothing else available. I think Skylighter covered liquids and colours in a newsletter. I think they called them ghost mines.

With "ghost" being very much the correct term!!
