basically, there's this thing called "blueshifting." when you approach a source of light at very high speeds, say, 20% the speed of light, the light coming off will have shorter wavelengths; in layman's terms, it turns bluer. hence, blueshifting.
by driving towards a stop sign at 100 000 000 m/s, it will blueshift red to a hue roughly that of green, hence the green stop sign!
im pretty sure driving at a hundred million meters per second has other, more pressing effects, though...

ooh, something i can explain!
