Chestnut iridescent is very different to Jo Sonja dark background is not required for Chestnut but you would need to experiment on white unless someone else already has.

The paints I have are Jo Sonja , I ordered some thinner from Terry at Chestnut thinking they were all the same ,
Will the Chestnut thinner work with the Jo Sonja paint ??

They are all acrylic so any acrylic flow medium (or some water!) should work to thin them.

I use the Chestnut irridescent paints on a white base. They work fine for me that way.

Thanks Paul , I contacted Chesnut and they were unsure if the flow medium was OK to mix between brands , as you say it should be OK , I will give it a test

I would go for a flow medium of some sort and not water. Water tends to make paints go transparent if thinned too much

Jo Sonja Iridescent colours are coloured mica in an acrylic carrier. The carrier looks white but dries clear.

Chestnut Iridescent colours are coloured acrylic with mica added.

So as said above they both work differently. But I have used Jo Sonja on dark colours, specifically blue, as well as black.

Jo Sonja iridescent paints have no pigment. They are reaction paints. The different colours appear due to differing thickness of the particles causing refraction/reflection of different wavelengths of light.
