when the temperature of the air is 25 degrees Celsius, the velocity of a sound wave traveling through the air is approx.

c = sqrt(adiabatic index*R*T) ~= sqrt(1.4*287*298) ~= 346 m/s.
At 25o C, the speed of sound in air, in a standard atmosphere, is about 774 mph.For more details and formula for calculation, see Related links below.
In HVAC terminology, a diffuser's neck velocity is defined as the velocity of air traveling through the duct work to the air outlet or inlet. The difference of the face velocity is this is a measurement of fume hood performance.

In dry air it is 346 metres per second. As humidity increases, the speed increases to 348 ms-1.

No, velocity and color are independent. Color is determined by frequency, and speed is determined by what material the light is traveling through.
That would depend on the medium which the light is traveling through.
The velocity of sound in the air is about 330 m/s. The velocity of sound in a liquid is about three times that. But varies widely with liquid. The velocity of sound in a solid body is about 4 or 5 times that of the sound in air. But once again, it varies widely with the solid. hint, check the values for lead and tungsten.
