Vivianite?

[HaroldRoth]

Has anyone tried vivianite as a watercolor pigment? A friend posted about using it in acrylics and I did some research on it because it's an earth blue, sometimes known as blue ochre. Daniel Smith used to carry it in their watercolors, but now they don't. Apparently it changes color, becoming darker with exposure to light. I like it's bluish grey color and sent for some powdered pigment from Australia, one of the places where it's mined. I just wondered if anyone had used it, including the Daniel Smith version when it was out there.

I have never tried it. Will be interested in the replies on this.

No, not tried it or even heard of it. Sounds interesting though.

Nope, never heard of it either. That said, I would generally steer clear of pigments that change under influence of light.

Never heard of it either, I like the look of it though (I love granulating colours)

Never used it, but it looks like it would be perfect for ocean paintings
