This reminds me of a slab of marble or granite with magnificent color running through it. It is an example of paint pouring. As with most things in life, it is much more difficult than it appears.
The brownish looking color is actually a metallic gold which brings incredible life to the piece when the light strikes it.
If you are interested in paint pouring, there are lots of videos on YouTube that explain some technique to help you get started. From there, you develop you own style, much like painting with a brush.
Does this technique interest you? Please leave your comments to help me guide future postings.
