When you see an ARC in an environment you feel relaxed.
If you visually continue the line of each end, they would eventually join in a circular motion.
It creates harmony.
An Arc is relaxed.
Eg. Person relaxing in comfy chair, or a curtain draped over a window.
The path Leonie has photographed shows a sweeping curve- your mind continues the circle - it feels complete.
green seems a great colour to represent an arc.
Nature demonstrates so many arcs!
They are relaxed, and calm, yet have a slow energy as they grow.
