Originally the colours were all browns and oranges, but the individuality of the three sisters fused into one was getting lost A few years ago I took a submarine ride on Isla Roatan – sunny day, clear water – and every creature we encountered, regardless of its’ actial colour, had this eerie blue cast. So that was the inspiration for the colour change initially, but it also allowed me,in terms of colour anyway, to define the three sisters more clearly. I’d love to give an explanation on how the circle happened, but I can’t. I did not even notice it until you mentioned it. Glad you folks like it.
