A First Grade Lesson in the rainbow order of color hues.
A rainbow spans a spectrum of colors which the human eye translates to color vision. In the acronym Roy G. BiV, the colors are arranged in a rainbow order of decreasing wavelengths, beginning with red and ending in violet. The kindergarteners develop "Roy" with painted Red, Orange, Yellow, Green, Blue and Violet tempera colors. The painted sheets are cut to construct "Roy's" hair and bowtie.
