Lens-Artists Photo Challenge #98 is by Leya: Delicate Colors. The first thing that comes to mind is flowers.
Gardens in springtime, when the green is new
A graceful swan on a rippling lake
Trees in fog
Sunsets are sometimes brilliant, but sometimes their colors are delicate.
Wanderlust & Wonderment 
Gorgeous photos!
Wonderfully delicate! I especially love the last one!
Beautiful. Nicely presented. (I like the round ones. Good for flowers.)
Thanks!
