It reflects a red color.
Why are some red ribbons of a brighter red than others?
When they reflect a great many red rays, they are of a bright red color; but when they reflect only a few red rays, they are of a dull red color.
Upon what does the brightness or dullness of a color depend?
It depends upon the number of rays of that color reflected.
What variety does this produce?
It produces a great variety in the shades and tints of color.
Where may many of these shades and tints be seen?
In the pretty flowers that grow in the woods, fields, and gardens; in the beautiful tints of the leaves in autumn; and in the plumage of the birds that visit us every spring, and cheer us with their songs.
What may these things teach us?
