Colours Of The Past Present & Future
8 Answers
What colors best represent the past, present and future please?
Answers
Using Doppler shift, approaching light (future) is shifted towards blue, and receding light (past) is shifted towards red. Light at the present will have no shift and therefore neutral. So past will be red, future red and now any neutral colour.
