These "shades of blue & green" are from a favorite day on Lake Michigan when the elements were backwards.
Normally, the air is clear and the water is a bit murky from the action of the waves. On this super calm morning, the water was crystal clear (look at the rocks!), but I could barely pick out the horizon. A heat haze was hanging over the water. It was still and gorgeous.
I hope this moment of delight gives you some room to breathe.
