Hi Nura! Stonehenge is one of our most versatile papers and every Stonehenge shade has the same characteristics. You could use watercolor on Stonehenge (including the Colors Pad). It isn't sized for watercolor paint, like our Stonehenge Aqua range, but many artists use Stonehenge with watercolor.
If you're interested, take a look at our Stonehenge Aqua range: https://legionpaper.com/stonehenge-aqua
on this part of the site it does not bring up to use watercolor, but this link,
https://legionpaper.com/stonehenge
shows that it is. Does that mean that the Stonehenge colors do not take watercolor well?
