The rainbow does indeed go from warm colours to cold colours, so I'm not sure I understand why you think I failed to understand.
Nope. For a start, Blue is the coldest colour, it is in the middle of a rainbow (Plus it's an exercise about people's variable perceptions, so unless every time that you've done this exercise it was with the exact same group of people, you did a different exercise each time.)
