The "whiteness" of an LED usually refers to its color temperature, which is measured in Kelvin. The majority of LEDs are "cool white" and fall in the 6500K range:

Be aware that Quark "neutral" is around 4000K; it's meant to look similar to a bright incandescent light, not attempt to be a middle-of-the-road white.
Actually i thnik you're confusing them with the older Quark neutrals, which were of a 5C tint or even lower colour temperature. The new Quark neutrals have a much higher colour temperature and some have reported them to have green/blue tints and indistinguishable from cool white variants. It's supposedly due to the higher bins that the new neutrals use.
Hello Orgad, Hello all,
My first post, although I have been lurking for years...
As per other threads in this forum, and put in a few words at the risk or paraphrasing, the "default" tint for a LED is "cool white". Manufacturers add sulfur to the LED to add yellow tint to the bluish tint to make it "warmer". The sulfur absorbs energy and results in a less bright light output. So a "Cool white" LED will be brighter than a "warm white" LED of the same kind, for example.
In some applications, like outdoors, a warmer LED will render colors (in particular greens and browns) better than a cooler LED would, and details of the landscape may be more visible than if they were illuminated with a brighter cool LED. I hope this makes sense.
So if I wanted maximum efficiency and interested to draw the maximum brightness output from a light, and mostly use the light indoors, I would go cool white, but if I use the light mostly outdoors, and want to see more intricate details and interested in a better color rendition, but at the cost of a slightly less bright light output, I would go neutral white.
