Using tree sap resin as colouring

Hi,

I want to use native tree saps as resin colour but don’t know what I can mix these saps with and then use them as colour.
Many saps can be boiled down or even watered down to make the colour, also turpentine is a possibility.

Which of these options would be best for mixing into the resin?

If I want a hard resin for a sculpture, which resin should I choose?
