Red light and blue light travel the same speed in a vacuum, however they travel different speeds when traveling through any medium other than a vacuum.
In most media, blue light has a higher index of refraction (usually denoted with the letter n) than red light. The higher the index of refraction, the slower the light goes compared to its speed in a vacuum. This relationship is governed by the following equation: v = c/n where v is the speed of light in a particular medium, n is the index of refraction of light in that medium and c is the speed of light in a vacuum. Since red has a smaller n than blue in most media, red travels faster then blue in most media.
The index of refraction is determined by solving Maxwell's equations for a particular frequency and a particular medium.

Why did Einstein state that you can travel faster than light but not at the same speed at which the light travels?
Einstein stated that nothing can travel faster than light.
Where would you end up if you could travel faster than light?
If you could travel faster than light, then you could also travel to the past. This is related to the definition of simultaneity, in the Special Theory of Relativity.If you could travel faster than light, then you could also travel to the past.

Do LIGHT WAVES TRAVEL FASTER THAN SOUND WAVES.?
No light travels way faster
Do sound waves or light waves travel faster?
In air, light waves travel about 871 thousand times faster than sound waves.
Which wave of light has the greatest frequency?
nope. because then it would travel faster than light, which is currently impossible.
Does red light travel faster than blue light?
No. All colors travel at the same speed. It is called "the speed of light".
Can echoes travel faster than light?
No. Nothing can travel faster than light.
What is superluminal travel?
Travel faster than the speed of light. By definition, Superluminal is "Faster-than-light (FTL)"
Does any aircraft travel faster than light?
No. Faster than light travel is impossible in any case.
Do asteroids travel faster than light?
No, nothing travels faster than light.
Is the beat of a flies wing faster than light?
Nothing that has mass can travel faster than the speed of light. A fly's wing has mass, therefore it cannot travel faster than light.
Why did Einstein state that you can travel faster than light but not at the same speed at which the light travels?
Einstein stated that nothing can travel faster than light.
Does shadows travel faster than light?
no
Does gravity travel faster than light?
No.
Can meteors travel faster than light?
No
Can air travel faster than light?
No.
