I think the absence of color would be clear or see through. How can you have black when there is an absence of color?

Black is the absence of all color.

White is the presence of all color.

Can you please elaborate on this. I'm intrigued.

Black is absorbtion of all emitted (visible) light,
If you define light as bounced off fotons from a 'coloured' surface, then black isn't a colour.

Go to paint, on the "colors" menu, click "edit colors"

Play with the sliders. What does it look like when they're all at 255, how about 0?

In terms of how the light actually works and stuff, black is no light.

An object that is pure black will absorb 100% of all the light that hits its surface.

An object that is pure white will reflect 100% of all the light that hits its surface.

Humans see light in three percieved colours - red, blue and green. These correspond to specific wavelengths of light. The actual colours themselves don't really exist, colour is just how the brain percieves those wavelengths. The RGB colour palette used on computers was formed because of this fact, which uses amounts of . Pure red is 100%-0%-0%, pure blue 0%-0%-100% and pure green 0%-100%-0%. If you maximise all those three colours - ie 100%-100%-100% - you get white. Take all colours away - 0%-0%-0%, and you get black.

In terms of light it's actually white that has all colours mixed up, and black has none.

However, on newspaper ink, black is the mixture of all colours.

I like that analogy.

But I agree with the theory of black being an absence of color. Also with MQ the color we determine to be black as a very dark gray, such as the background of the forums.

Think of black holes.

I think about black holes sucking up our planet, not about the color Black. :roll:

Actually, it's not. Black dyes are usually very dark red, very dark green, or very dark purple. Unless they're made in the middle east with Benzene - then they're black. That's against EU law, though.

I think we can safely say it's a color because many things are named "Black _____" and it's most of the colors combined. If it has colors inside it, it's a color.

right let me explain this to people who dont understand.
btw you will go over this in last year high school...

black for vision, is a shadow. there is NO, light in a completely pitch black shadow therefore its absence of light.

normal l9ight is called white light, because it has ALL of the colours coming from it.

to make a red light you put a piece of red transparent paper infront, because something that is red ONLY lets red through, therefore all the rest of the colours will be blocked by the paper.

this also relates to spectrums where you split up the white light and it produces all the different colours in lines.

rainbows are sunlight split up by the rain - just a very big spectrum across the sky.

not too sure if this is clear or not as its a lot to put down, if anyone wants me to clarify something just post.

@chris, arent black holes big-ass stars that have imploded which makes a mass of nothing-ness in space?

Care to clarify the color white? I don't understad, if all colors combined = brown, wtf why does all colors coming from a area = white?

White light is formed when all wavelengths of visible light are emitted or reflected from something equally. So, technically, white light has brown and red and green and blue and purple and everything else in it.

On the RGB colour palette on a computer, FF-FF-FF, or 100% Red, 100% Blue, 100% Green, makes white.

Your 'all colors combined = brown' idea comes from the idea of mixing dyes, inks, paints etc. Red + Green + Yellow + other colours does make a horrible shade of brown, but considering dyes and paints is fundamentally different to considering different wavelengths of light.
