R“ is for “Rainbow

I Love colors and I love “Rainbow“.

A “Rainbow” is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines on to droplets of moisture in the Earth’s atmosphere. It takes the form of a multicoloured arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

In a “primary rainbow“, the arc shows red on the outer part, and violet on the inner side. This rainbow is caused by light being refracted while entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.

In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, red facing toward the other one, in both rainbows. This second rainbow is caused by light reflecting twice inside water droplets.

  1. Hello Dora,
    I’m a painter from France who came to your blog through twitter links.
    I just wanted to tell you how I love your alphabet. I just found the poetry of Paul Klee here and the colors of Hundertwasser. Hope you are ok with this association. From France. Kind Regards.

  2. Hello Hazlo,
    Thank you so much for your comment! I am definitely ok with the association to Paul Klee and Hundertwasser. I am a great admirer of their art.
    Happy Sunday!
