These highly concentrated water based acrylic colourants can be used to colour water based products, like varnish and paint, and also grout, filler and water based glue. My Colour can also be used to tint Walnut Crystals in solution and we have also used it, successfully, to colour Epoxy Resin - although this does slow the drying time, so proceed with caution.
My Colours can be mixed with each other to create new colours and also added to pre-coloured bases to change the shade or colour. Use the basic principles of the colour wheel when mixing colours together, but bear in mind My Colours are extremely strong.
