In the rainbow sequence, which color is second to last?

• A. Red
• B. Indigo
• C. Violet
• D. Blue

Answer: (B)

In the classic seven-color rainbow, colors are listed in order from red on the outside to violet on the inside: red, orange, yellow, green, blue, indigo, violet. The second-to-last color is the one that comes right before violet, which is indigo. So indigo sits between blue and violet, making it the second-to-last color in this traditional sequence. Some versions omit indigo and go from blue to violet instead, which would change which color is second-to-last, but this question uses the standard seven-color lineup.
