George's Hard Rock Café 'Save the Planet' crayons

You might have noticed that the colour looked rather strange in the last sketch of the view from the wedding reception at Walton Hall. My great nephew George came over to our table to see what I was drawing. I told him that I'd like to add some colour but I'd left my artbag in the car. He ran off and fetched me his set of Hard Rock Café 'Save the Planet' wax crayons. These giveaway crayons come in the three primary colours so I had to mix the greens of the slope and lake from varying amounts of the yellow and blue.
