Not aware of the show you mention but we have one over here called Watercolour Challenge.
Contestants show up in scenic locations across the country & paint what they see.
Their work is then judged & the winners of each episode eventually meet in the grand final, winning a cash prize, an easel & a bunch of brushes.
I enjoy watching mostly because the look of rage on the faces of the losers makes me laugh.
I tried it once, started painting a swan in a canal but it swam off way before I could finish, I mean, how’s that meant to work.
