Rainbows

Rainbows. What images they bring to our minds. There is the coolness of the rain, which is really appealing now that it is summer here in the desert. The dictionary defines a rainbow as " The arch of prismatic color formed in the sky opposite the sun and caused by refraction, reflection, and the dispersion of light in raindrops falling through the sky." The red rocks of Sedona appear different in this magical light.
Sun, sky, rain...what a series of images they evoke in our minds and souls. 
The  use of color is something we always think about as artists. I use watercolor, or the opaque form called gouache, in my calligraphy. Even one color in all its tones and hues and density can create a  rainbow effect. The  sheer power of which colors we choose to place  near, next to, or touching each other, can evoke a whole other mood or impression. We have to plan these effects. Mother Nature seems to just get it. And in this picture she did it twice!
 I look forward to that  summer rain and the magical first glimpse of those gently rounded shapes of color that peek out from the clouds, just  before it  come out in full rainbow glory. 
  Any thoughts about your personal rainbows?
