The Wonderful Color White Segment #6 

There is precious little about Helen on Wikipedia.

I think this might still be her real hair, but later when she had cancer, she was definitely wearing wigs. Her own hair was a bright and very silvery white. All, I know, is I miss her!

I'll never forget an exercise an art teacher did one class - with a projector that accepted colored glass slides, he lined up one color after another, and the more slides he added, the paler the color on the screen. When all slides were installed, the screen was white.

I was taught that white is the absence of all color, and black was the presence of all color.
