Just a quick post with my second attempt with the Zig Clean Color Brush Markers:
This is the Jumbo Dahlia stamp from Stampendous, on Tim Holtz watercolor paper. This was colored with no water, just the brush markers themselves. I heat-embossed the image before coloring.
The markers blend quite well on watercolor paper without any water. Catherine Pooler says they work well on Bristol paper too.
The colors I used are Carmine Red, Pink, Light Pink, and Light Violet. It turned out so bright, if I use it on a card I think I would want to add a vellum overlay.
