In primary school, blue and yellow fingerpaints made a lovely green, but green and red just made an icky colour charitably called 'brown'.\n\nYet TVs and montors tend to use an 'RGB' system where, I'm told, red and green in combination make yellow. I made more than a few colour wheels in primary school, and this makes no sense to me.

You are confusing emissive mixing with subtractive mixing. When dealing with pigments, one customarily uses the colors Cyan, Magenta, and Yellow as primary colors. This is because you are actually dealing with a subtractive spectrum. The colors of the pigments are the part of the spectrum that is not absorbed by the material, so mixing them is not an additive procedure, but a subtractive procedure. Mixing all of the three colors above will not get you white, but (in a perfect world) will subtract every color from being reflected, giving you black, the absence of photons. In the real world, the pigments are imperfect and you actually get a murky dark greenish color, which is why an independent black ink is added to printing processes (CMYK).\nRed, Green and Blue are primary for the emissive spectrum, these are used for mixing colors of pure light (ie., CRTs and LCDs). Mixing all of these colors (use red, green, and blue filters in front of white lights) will get you white, as it should. See the article below for more detail.

I can't answer most of the stuff, but the greenish hues depict being in the simulated computer world, (The Matrix). The old computer screens were known for having a green hued screen.\nCyberNara

Smern was a general colour, I invented.  It doesn't exist but its not green, blue, red, white or black but its useful to talk to people about their reaction to what people wear.  Its use is to say; regardless of its colour what other attributes are important in assing a person's taste in clothing. eg:  I brought a sports car.  Q. What colour is it. A. Smern, what else would you like to know.\n\n'Smern' is my example of an original thought, and my point is that an original thought would not mean anything to anyone.  Original thoughts are beyond expression, they would just be a pause in a line of thoughts.  We have to relate our thoughs to what is already understood.  In this way ideas are developed and assimilated.  If smern catches on, it will not be original except when I first used it.\n\nIn regard to you detailed comment. I think there is a new quality to an opinion even if its been used before because its being used now, by this person, in this place.  The next moment is original so what ever happen in it is new.  Your question is an old one but it never had this response before did it!  \n\nYou have never been smerned before have you? and I have never smerned YA before but next week you might find smern in Google, that would be new.  Wow.

Of course, sunlight is made up of many colors.  However, we can think about "original" (or "monochromatic", or more realistically nearly monochromatic) yellow lights from other sources (like a laser).\n\nWith the composed yellow, you can separate the green and the red back out.  One way to do this would be with a prism.  While the monochromatic yellow light would just stay yellow, the composed red+green would separate back out, with each color in its position in the rainbow.\n\nA more sophisticated way to do this would be with a spectrometer.  The monochromatic yellow would show just the one wavelength, in the yellow part of the spectrum.  The composed light would show two wavelengths: one each in the green and red parts of the spectrum.  It would show no light in the yellow part of the spectrum.\n\nSnawshia is right about the speed: in a vacuum, they'll have the same speed.  In other media (water, glass, etc.), each color may have a slightly different speed.

This may be of little or no help but all I could think of after reading this question was the scene in "Mask" (the 80's flick with Cher). The character with an odd face is dating a blind girl and he gets a bunch of stones.  He hands her a cold one, and says "this is blue" then hands her a hot one and says "this is red." For other colors like green and yellow, I would use sent. Like a glade plug in that smelled like spring.\n\nAll color truly does is describe something to our eyes.  Since they cannot see, you must find a way to describe it to one of there other senses.  Maybe white is a feather; maybe purple is a flower...

I believe the answer to this is because they have trouble with colors of the same hue. Both of my brothers have lived all their life with color blindness and I notice that they mostly get blue and purple mixed up. Same goes with the traffic lights; they have problems distinguishing between red, yellow and green.

The colours are a bit dark, use more orange and yellow.\nGood idea though

This is a question I've actually thought about before, but the problem is, there is no way to tell if everyone sees the same colors.\n\nFor example, I could be looking at a stop sign.  It is red.  I know what red looks like.  But what if another person had a different perspective of colors?  They are seeing, we'll say, what is green to me, but their whole life, people have called that color "Red," so they think it is red.  They have no way of knowing what red is to me, and vice versa.\n\nI'm sure there are some tests, but if you're just mixing up colors, it would be hard to tell.\n\nWhat a weird thought, huh?

Well it's like lemons are called lemons, and that is also a color. It could be whoever brought oranges to this country or even Europe called them oranges because of the color. Not knowing what they were at the time. Just made it easier to describe them. you know those orange things. they know the color, but not the fruit. So that could be how they were named. Hope this hellps you.

Hi, yea your correct...\nColor is represented in a hexadecimal notation. Therefore, if you choose Computer, it will get the nearest hexadecimal representation for it... Therefore purple\n\nBut be aware thats a wrong syntax... I advice you to stick with webstandards... Take a look at the links I provided for you to learn more about these stuff..\n\nI recommend you to use styles instead..\n<body style="background:red;border:1px solid black">\n<body style="background:#ff0000;border:1px solid #000000"> \n\nWith styles, you could do alot! You can add anything you want. But you would say it will be messy! and I agree!\n\nI URGE you to take a look at these fun examples!\nhttp://www.w3schools.com/css/css_examples.asp\n\nAnd see yourself! Learn the new modern way... Trash the traditional way :)

primary and secondary colors.\n\nThe primaries are red, blue and yellow.\n\nThe secondaries are formed by each pair of primaries.  Ie: orange (for yellow and red), etc...

the answer is "colors" \nolive and green are colors\nyou can't see the word colors, only what colors are\nand it has 6 letters in it.

You could use different colors for the three generations, and only use 1/4 of each graph box.\n\nFor example, if red is the first generation, and blue the second, and green the third, show the red generation in the upper left or NW corner of the box, blue in the NE corner, and green in the SW corner.\n\nThe other alternative would be to show this on three different pieces of graph paper or sections on the same page.  The benefit of the three pages is that you can lay one on top of the other and see the previous generation through the paper, and not have to recopy it.\n\nGood luck!

Add a touch, a little touch of red to yellow, this may help, if applied thinly it can look like skin.\n\nAlways work using light to dark, so if a light colour doesn't work you can go over it.\n\nAlso try different colours, you may find that playing with ideas lead you to other pieces of art, it is also a good way to get to know the paint you are using, how to mix to get light/dark colours etc.\n\nAlso never use white, it makes the colour look to solid, and takes away from the pictures quality

You may not realize it but in one qhestion you have asked for knowledge that is gained taking a university level physics course.\n\nSince I am a lousy typist, I will give you some clues that should allow you to visit Google and gather the answers you are looking for.\n\nThere are twi type if color mixing.  The additive method, used by painters, where you mix yellow and blue to get green.  \n\nThe subtractive method, used in optivs and video technology, where colors are filtered out as opposed to added in.  In this method the primary color are differet.\n\nIf you want a much more thorough explanation, you may want to examine the study of "Chromatics".  At look at how rainbows are created might help as well.\n\n\nBest of luck,\nJeffrey

Since you need simple and portable, how about starting with something that uses light and prisms to create the spectrum? \nFrom there, you could go to show how rainbows are created ( where the light must be, what the sequence of the rainbow spectrum is) or compare how light colors mix compared to how m=paint colors mix.  I don't know if that is appropriate for the 10 th grade.  But working with light and prisms is always fun.\nmagnetism is always fun, too.

I think you are making connections which are not really there.  If you look hard enough, you cant find numeric connections with a lot of things which are coincidence and have no meaning in reality.\nThere are 10 planets now, not 9 (and not 7).  We define our colors very arbitrarily, the same with music notes, there is no real physical meaning behind why green and blue are not considered shades of the same color.  Who decided that Asia and Europe should be different continents, one might very easily make thw argument that should really be one big continent...and India is often times refered to as a "sub" continent.\nI dont see how any of these things would influence the number of dimentions there are, but at very least, they are fun to think about for novelty purposes.
