Depends on what country you were from. Yellow lights are commonly known as "French fogs" as they were mandatory in France for many years. The yellow color spectrum is the easiest for the human eye too see with the least strain. This is around 4300k. Guys that think blue tinted lighting is cool are dumb, uneducated, and flat out dangerous. Blue is the lowest wavelength on the color spectrum and as such the LEAST amount of visible light. The lumen output is significantly decreased as any blue filters filter out all the good color/light.
Many people still choose yellow Fogs for this reason. They look different as their not very well used anymore. Check out:
