Crayon Colors and Length of Lines

Does the color of a crayon affect how long of a line it makes? (Editor's note: If you use an entire crayon, this project could take a long time. One way to test this would be to mark equal, short distances on different colored crayons. Draw a line back and forth down a very large/long until you reach the mark on each color. Count the number of lines on the paper and see if they are the same for each crayon.)
