Are you
Colors?
I am all of the principal, the primary, the parent-
Everything has a color and there such things as primary colors and the hint suggests this.
I am untainted, but made through contamination.
Mixing colors.
I am peace, I am death;
Peace may be blue but death is black.
I am good, and I am safe.
Other colors.
I am new, I am brilliant;
Green can mean new but brilliant may mean purple.
I am clean, and I am perfect.
Other colors, maybe white for clean.
My kind have caused strife when compared to others,
Race.
The hues of a bee, we no longer stick together.
Yellow and black?
In this way I may not be peace, I may not be good.
We may be the ones storming down the neighborhood.
Still race.
Up in the sky, down on the ground,
Blue sky, brown dirt.
Right before your very eyes-
We recieve color in our eye cones.
Right here, right now, can I be found.
Black and white on my screen.
Multiple meanings have I, multiple lives I live,
There are many different colors.
OP's Edit:
The specific color is "white"
I am all of the principal, the primary, the parent-
I am untainted, but made through contamination.
White is made up of all colors mixing together, with black being no colors together.
I am peace, I am death;
White is a symbol of peace for many countries, and in China white is the symbol for death. The rest are additional symbolisms related to "white".

As found: race. "White", "Asian", and "Black" are some of the largest racial groups today, and there is a large amount of tension despite the progress.
Up in the sky, down on the ground,
Clouds in the sky, many human-made buildings or other items on the ground, white flowers and other flora, etc.
Right before your very eyes-
Right here, right now, can I be found.
There's white on the screen right now!
