As fast as any other light (ie 299,792,458 m/s or approx 186,000 mi/s). The confusion with "color" (frequency) may arise from the "slow blue light" (Cherenkov radiation) which pervades the heavy water tank around fission reactors
Yes, they travel some fast!
Copper is opaque to light - light can not travel though it.
how fast does the colour blue travel
the speed of light
it can travel from 380nm [nanometres] to 740nm
Darkness is the absence of light and will therefore travel at the speed of light (6x108m/s)
yes

Speed of light.
Approx 9.46 trillion km.
