The same.
does the color of a lease affect the velocity of the light waves projected by the laser?
No as they are both electromagnetic waves so have the same velocity but have differing wavelengths and frequencies.
The velocity of the light waves must be given before the frequency can be find.
Electromagnetic Waves all have constant velocity which are equal to the speed of light. It is only the frequency of the wave that differentiates ie between radio, gamma, X-ray. The velocity is always fixed at 3 x 10^8 ms^-1 which is equivalent to the speed of light.
The velocity of light (and other electromagnetic waves) depends on the medium through which it is travelling.

There are some situations in which waves move faster than the speed of light; but in no case can this be used to transmit matter, energy, or information, at a speed faster than the speed of light in a vacuum.
It isn't - at least, not in a vacuum. All electromagnetic waves have the same speed in the vacuum. Both visible light and x-rays are electromagnetic waves.
Light waves are made up of electrical waves and magnetic waves that are perpendicular to each other and support each other, they are also perpendicular to the direction the waves are traveling so there are no vibrations in the direction the light travels.
Electromagnetic waves in a vacuum all travel at the same velocity, the speed of light (about 3 x 10^8 m/s).
Sound waves are longitudinal waves in air. Velocity of sound waves in air at NTP = 332 m/s.
