White gets cold because it reflects all light.

When the human race started it was black because it started in Kenya a very sunny environment.

As the human race adapted to other environments it became white among other colors.

Because surviving in environments that were not as sunny did not require melanin.

Neuromelanin is the dark pigment present in pigment bearing neurons of four deep brain nuclei.

In humans, these nuclei are not pigmented at the time of birth, but develop pigmentation during maturation to adulthood.

if you mean white as in personality white then its a pretty shit similie/metaphor whatever especialy to bring to a thread about race, you should watch your words fam cos you could upset alot of people, maybe on a different day i wouldve got mad about that but im giving you the benefit of the doubt

I used no like or as no simile or metaphor.

I described the properties of white and black.

I mean white as in the light.

We live in the visible light frequency spectrum.

Everything I describe to you so that you can understand or "SEE".

Has to reflect properties of the visible light spectrum for you to "FEEL ME"

If I go outside of that spectrum at this time you will not "HEAR ME"

i could say white is clean and pure and black is dirty and unclean but it would be pretty fucking inapropreat especialy on this thread dont you think, wise up

Similarly it is not even really the qualities but we call it the qualities to describe it's properties because it is acting like those qualities.
