So, what I’m taking away from this is that, if I ever see a blue rose, it’s already too late, and the object moving at relativistic speeds toward me has already probably ignited a thermonuclear reaction in the air around it, but the light from the fusion bomb before me has not yet reached me?
It’s fine! My math says the rose is actually moving away from you, at around a third of the speed of light.
At this speed, it orbits the earth (at sea level) 2.5 times in a second. Maybe it shoots for the moon, which it reaches in less than 4 seconds. Or it might be on its way to Neptune, which will take it 12 hours!
Also, if this red rose was actually moving towards you at the same speed, I guess it would look black, since you would receive a wavelength you can’t see? Ignoring the pesky thermonuclear reaction stuff…
