From the web page below:\n\n"Mars is 20 degrees above the western horizon at sunset and sets near 11:30 p.m. Look for Mars near the new moon on May 2 and again on May 31. Take care to avoid looking at the Sun as both the Moon and Mars are low on the horizon after sunset. On May 30, Mars is at the left end of a long celestial line consisting of Mars, Moon, Pollux, and Castor, the two brightest stars in the constellation Gemini."

it is a reddish color.  This is from the iron deposits on the surface that have oxidized(rusted).  Its like a rusty planet.

The Earth and Mars do not orbit the sun in perfect circles, they are ellipses.\nSo sometimes the Earth is closer to the sun than other times, and sometimes Mars is closer to the sun than other times.\nSo if the Earth is farther from the sun than normal at the same time Mars is closest to the sun, and this happens when both planets are on the same side of the sun, then we are closer to Mars than any other time and therefore we can see it better.

Why SUN appears red in dawn? (and dusk)\n\nThis is the time when the sun's light travels through most atmosphere to reach us. The small particles of dust scatter some of the light and most of the light scattered is blue light. As the blue light gets scattered out of the original white light the light that reaches us has a bredominance of red light and so the sun appears red.\n\nThis also explains why the sky appears blue during the day as we see much of this scattered light coming at us from all directions. It also explains why when we see the sun through smoke it appears very red as well and why we see great sunsets after days with a great deal of haze or after some event such as a huge volcanic eruption somewhere on the earth gives us a long sequence of beautiful sunsets (and sunrises) as the eruption of Mt Pinatubo in the Philipines did in the 1980s

RED ... the color of passion. A very uplifting color.  Gives you energy.

It would be like Mars.  Mars has an atmosphere, enough that it has wind, dust devils and giant sandstorms.  However, there is not enough incoming solar radiation (aka insolation) trapped by the atmosphere to keep it warm.

It has to do with the depth of the stone when found in the mine. Blue to green would be from a specimen closer to the surface and the green to red is buried deeper within the earth. Of course light plays a roll in the color prism of the alexandrites.

Red because it can represent so many things. Love, passion, anger, chaos etc.

Mercury: Gray\nVenus: Bright white\nEarth: You have seen the pictures. Mostly blue with lots of white spots and swirls and maybe some green and tan for the land.\nMars: Pale salmon color.\nJupiter: White with horizontal brown bands.\nSaturn: Honey color\nUranus: Light blue\nNeptune : Darker blue.\nYou can see the pictures I have taken of these planets at the source below. I have tried to make the colors match, as closely as possible, what I really see in the eyepiece of the telescope, except for Mars which just looks too plain without enhancing the colors. For Mars, be sure to click on the "Click here to see more Mars images." link and see the one truly natural color picture about half way down the page.

WHY IS THE SUNSET RED?   \n\nAs the sun begins to set, the light must travel farther through the atmosphere before it gets to you. More of the light is reflected  and scattered. As less reaches you directly, the sun appears less bright. The color of the sun itself appears to change, first to  orange and then to red. This is because even more of the short wavelength blues and greens are now scattered. Only the longer  wavelengths are left in the direct beam that reaches your eyes.   \n\nThe sky around the setting sun may take on many colors. The most spectacular shows occur when the air contains many small particles of dust or water. These particles reflect light in all directions. Then, as some of the light heads towards you, different amounts of the shorter wavelength colors are scattered out. You see the longer wavelengths, and the sky appears red, pink or orange.

It is the red planet because it is red.  I don't know if the planets were given the names first or the Gods, but either way Mars was the God of war, which I am sure is why that God is associated with that planet.

The latest in graphix design is called "The Egyptian Technology". Computer researchers are now exploring the depts of the pyramids to find out how the pharoah and his people came up with the 3-D option of making pyramids. However the martian government has now offended the researchers in this regard. The martians claimed that the pharoahs how are now in mars have opposed to the research because of the fact that it involves opening of the graves. The pharoahs believe that once the tombs are opened then they have to come back. They quite like the life in mars better than the life here in earth. Hence, the researchers have now takent he matter to the highest authority on earth, that is the UNO. The UN supreme court will now have to solve a dispute between the martians and the humans..\n\n\n---x--\nto answer your question - WHAT IS YOUR QUESTION!

Everybody is somewhat near to my answer but a truth behind is... Because of Fog and bad weather the only color Red is most aggressive to travel fast to the sight. You can see the red light from more far away when the weather is not good or there is somewhat fog, raining or sandstorm. The Green comes after that and is for Get Ahead... I think so...
