Simon searched a few drawers before he found a crumpled up piece of paper. He pressed the paper against the surface of the desk and worked out the creases. Stretching the paper out, he realized a drawing of a rainbow was on the front side. The image looked drawn by a child or someone younger. Looking at the rainbow closely, he counted how many colors presented on the page.
Approaching the door, he noticed a keypad. Paint resided on all of the buttons. Glancing at the number pad and the rainbow drawing, Simon began making the connection. He pushed a random combination and learned the code consisted of five numbers— he learned this because the door falsely beeped after the fifth digit. Simon tapped on his chin and examined the paper.
The colors of the rainbow consisted of five colors: red, orange, yellow, green, and blue. Red remained as the biggest arch followed by the corresponding colors. Blue's arch was the smallest in the group. Simon theorized the numbers on the pad with the same paint matching the rainbow would lead to the passcode.
Simon found the numbers immediately. 1-Blue, 4-Yellow, 7-Red, 3-Orange, and 9-Green. The only problem that needed solving involved the order of the numbers. Simon glanced back at the rainbow drawing and assumed the order is fixated on biggest to smallest arch. The musician did not have any other ideas.
He pressed 7,3,4,9, and 1 in order as shown on the child's drawing. Waiting a few seconds, Simon heard a 'ding' and witnessed the door open a crack. Smiling, he walked out the room.
