White

The Search for Roy G Biv has brought us beyond the rainbow, to white. However, I would be remiss as a science geek if I didn't point out that white light is actually all the colors of the rainbow, combined:

"Visible light, also known as white light, consists of a collection of component colors. These colors are often observed as light passes through a triangular prism [or a raindrop]. Upon passage through the prism, the white light is separated into its component colors - red, orange, yellow, green, blue, [indigo], and violet. The separation of visible light into its different colors is known as dispersion. ... each color is characteristic of a distinct wave frequency; and different frequencies of light waves will bend varying amounts upon passage through a prism."  
                                                                     ( Dispersion of Light by Prisms; The Physics Classroom )                                                                        

It was Isaac Newton who discovered that white light is composed of these different colors:

"Newton’s contribution created a new understanding that white light is a mixture of colored light, and that each color is refracted to a different extent. The different colors correspond to light with different wavelengths, and are refracted to differing degrees. This separation of colors is known as dispersion."
                                                                                        (Causes of Color: What is Refraction?)




 I'm not sure what type of caterpillar this is, but I think it's pretty cool-looking....

Bear grass at Glacier National Park...





A springtime favorite in my yard, paper white narcissus...






Clouds in Ohio, and in South Carolina...





This odd-looking Kentucky wild flower looks white, but is ever so slightly tinted with violet in places...






Seeds of the season with their fuzzy white parachutes, just before they fly away...






My son Colin's beautiful bride, Lindsey, in her shimmering white wedding dress last weekend...






For more beautiful examples of white found by others in the Search for Roy G Biv, visit the blogs of our hostesses, Jennifer Coyne Qudeen and Julie Booth; they will link you up!  Thanks for joining me on my journey into WHITE; hope you enjoy it!

  1. I'm glad you took up the info on white and light ... well done as well as these examples. From a wedding dress to flowers to clouds, all beautiful choices. My reason for not using too much white paint is the chalky effect. Obviously mother nature has perfected white.

    1. I'm not big on white paint, either, Mary Ann. I'd rather do a watercolor and let the paper serve as white than deal with chalky paint. You're right; this is really just an artist problem!

    1. Glad you like them, Julie! A science geek like me just had to say something about colors being the components of white light!

  8. Love this post Sharmon... and quite apropos as The Nobel Prize in Physics 2014 was awarded jointly to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources".... by creating blue light for L.E.D.s they now can create white light in a more energy efficient way. and congrats on gaining a daughter!

  10. Bear grass - most unusual for such a delicate and pretty flower. Also love that fancy caterpillar, never seen anything like it. I tried to photograph clouds but non were as dramatic as the ones you have captured.
