I see your point but I like to learn  more and why things seem to be  they way they are...  I like to learn  as much as possible ..Just like I pass on  useful info to my kid...She too loves to learn.. .  And yes that means  me learning what some of you find a waste of time.... To me it is not  

For example... When I read something  like this below....

To answer these questions, we must learn about light, and the Earth's atmosphere.

THE ATMOSPHERE

The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%). Argon gas and water (in the form of vapor, droplets and ice crystals) are the next most common things. There are also small amounts of other gases, plus many small solid particles, like dust, soot and ashes, pollen, and salt from the oceans.
The composition of the atmosphere varies, depending on your location, the weather, and many other things. There may be more water in the air after a rainstorm, or near the ocean. Volcanoes can put large amounts of dust particles high into the atmosphere. Pollution can add different gases or dust and soot.
The atmosphere is densest (thickest) at the bottom, near the Earth. It gradually thins out as you go higher and higher up. There is no sharp break between the atmosphere and space.

LIGHT WAVES

Light is a kind of energy that radiates, or travels, in waves. Many different kinds of energy travel in waves. For example, sound is a wave of vibrating air. Light is a wave of vibrating electric and magnetic fields. It is one small part of a larger range of vibrating electromagnetic fields. This range is called the electromagnetic spectrum.
Electromagnetic waves travel through space at 299,792 km/sec (186,282 miles/sec). This is called the speed of light.

WHY IS THE SKY BLUE?

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.
However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.

As I only copied and pasted  small parts of the page...More about this in full detial  can be read here  - > http://www.sciencema...m/sky_blue.html

It didn't take me long to read that above...I read it and think - Cool, I have learned something new.. This was indeed useful to me.. ...Learn something new every day  never can do any harm....Well not in my book...It is always useful to learn  about our planet... Religion is not going to give you these kind of answers.. Science has to ..and does what it can... So yes it is pretty useful

I hope it has helped  anyone else reading.... l meaning those who  don't mind learning something .new ....Science is never a waste of time in my pinion...But that's just me

Excellent that's my point. The sky is not really red but just looks blue. If it looks orange because if wild fires it's orange. If it looks blue because of physics it's blue. A color is a perception.

My point is  ...Your attitude  was - you don't give a rats as* WHY it is blue.. I was pointing out that we all are not like that, many of us will want to learn  why and what  about these sort of things.... What looks  blue  but isn't really blue... is interesting to find out  why this is ... So my post was not agreeing  with you directly...It was showing that  learning is the key and  interesting for a lot of  people... I know not all will care to learn  but  so many will.. It depends on the person and the subject I guess  

You agree with the person that said  If it look blue then  it must be blue,  we'd be color blind  if we cannot know this you said in agreement - Exactly.. Which  in a way is wrong.. Because it is not really blue.. it only looks that way due to light..The less blue light that reaches you, it will not look as blue .. more to a clear color..It is not exactly  blue in color...  You quoted a long post of mine that had this info in it

Unfortunatly typed words do not convey the spirit in Which I ment that "rats ass" comment.  It was more a pock at how much of science does not give credit to human perception.

By that logic nothing has a color... It just looks that way do to light. It's rediculouse. It dosnt really matter how or why it looks blue. Our minds perceive it as blue. Not that I'm not interested in how or why... But it is completely illogical to say something is not blue when everyone preceives it is as such. Color is a perception, it's preceived as blue... It's blue.

One last post before I head to the hospital...... Seeker.The post didn't say nothing has color ..it only speaks of the sky and why we see it as blue.. Just because it looks blue and we accept it.. Reality is .. it's not blue... We just accept it is blue because of the light.... That is all I am saying...And  the info I posted  got a few likes, so obviously  a few reading found it useful ...So learning these things  I guess is helpful...  Some will.. some wont  

Now I am off..  Please do not take my post personal.. I am just clearing up a few things is all . It would be pointless replying to this because I am off soon to the hospital.. I am gone for a while.... Catch ya later...  Cheers

Depends, what time of day? The sky doesn't have one constant color.

Yeah!!!!! Baby time!!!! Not personal promise but trust me I have argued with a pregnant woman on more than a few occasions--- a completely loosing concept. God bless.
