why does the color red attract heat? why is red a bad color{Blood,death,horror}?

Dark shades of anything attract heat. Light shades repel heat. Red is a color associated with different things according to your culture. In China, red has a whole different perception.

Iron will generally give a dark red flame caused by the excitation of the electrons in the iron atoms.\nOther common colors produced by other elements include:\nRed color= Lithium compounds such as lithium oxide,strontium compounds and calcium compounds.\nYellow color= any sodium compounds e.g sodium hydroxide or sodium carbonate\nGreen color=Barium, molybdenum, boron, thallium, phosphorus, tellurium, lead, antimony, or zinc compounds.\nBlue color=Copper, indium or arsenic componds.\nPurple color=Potassium, rubidium, or cesium compounds

BLUE FLAMES ARE HOTTER THAN RED OR YELLOW ONES ♥♥♥

Perhaps it is because red light has the least energy of all the colors of the visible spectrum.  It has the longest wavelength, thus the slowest frequency, slower than that of blue or violet, for example.  I don't know for sure if this is the reason the materials are not sensitive to it, though.

i dont know what u mean by the second question but for blood, i just make a tiny circle and make it red so it looks like blood.

Well I could make it as complex and confusing as some but I will keep it simple.  The color of a flame is determined by the material that is burning. The color also denotes temperature of a flame. (yes there are different degrees of hot). Sodium will give a yellow flame. Have a gas stove? Notice the flame has two colors of blue, the inner flame is a different shade than the outer shade, look at a match, the flame closest to the center of flame is yellowish while the outer is reddish. The center is hotter in both flames.\nAdding a chemical to the fire will change color, copper will burn blue, both from chemical and its flame hotter than the average yellow fire.  The quantity of flame or size is why we cant tell the difference in heat from all these small flames and we say they are hot.

That is one of the reasons why.  The red light given off by those lamps not only helps make the body have a better appearance and look like it has more color, but is also enhances the make-up that hte mortician used on the body.  Another reason is that soft red light has a generally calming affect on people.  It may creep you out, but to alot of people it is a rather soothing color.  Stark white light is too sterile feeling to use, blue is too cold feeling, and the average amber color that most bulbs glow will not enhance the look of the body in the same way.  Light has a whole lot to do with making something look better or worse than it is as well as affecting the moods of the people in the area.

Red-eye is a phenomenon that happens only when taking photos using a flash. When taking photos in day light or when in high ambient light scenarios people’s eyes look normal. When taking pictures in low ambient light scenarios using a flash the result many times is redness in the people’s eyes.\n\nThe reason for the color red is simple – when flash light from the camera hits the eyes it penetrates and is reflected back from the retina. The color of the reflected light is red because the light is actually reflected from the red blood in the retina.\n\n(To read more, click the link below.)

depends on the color \n\nand it's not just effect on your emotions either.  color can have an effect on you phycically \n\nthats why doctors wear sea green.  they found that after staring at blood red for hours on end when they finished and looked at the white all around them thier mind would play tricks on them and they would see sea green and this would cause them to get nausious and vomit.  now when they look up and thier eyes play the same trick instead of seeing Green they see PINK which is very soothing.\n\nthey make the walls in asylum rubber rooms pink as well because when somone goes out of control they put them in a pink room it calms them down quickly.  for some reason it's difficult to be angry and or violent in a pink room.  unless of course you just REALLY REALLY HATE PINK.\n\nthere have been numerous studies on this subject.  try doing some actuall research on the subject.  i'm sure you will find plenty of source material  and most of it is likely to be more accurate than the answers you are likely to get here.

It's actually a bluish-green.  Look at your veins that come to the surface of your skin.  Blood only turns red when it comes into contact with oxygen.

Fire is the rapid combination of oxygen with fuel in the presence of heat, typically characterized by flame, a body of incandescent gas that contains and sustains the reaction and emits light and heat. (from www.straightdope.com)\n\nThe typical, bright, yellowish-orange upper part of a flame is due to the heating of unburned carbon particles.\n\nThe temperature of the fire and the material being burned are the factors that determine the color of the flame. The various colors of flames in a wood fire are due to the different substances in the flames.

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

The red color is found in many soils around the world.\nThe cause of that is the presence of oxides and hydroxides of Fe and Al.\nThose soils are known as ''weatherized'', usually done by many, many years of exposure to heat and humidity.

Red, just about any warm blooded mammal has haemoglobin that has an iron base and accounts for the red colour. Difference in colour only occurs in animals such as insects or spiders because they have a different base, spiders have a copper base.

Red has always looked good on me.  I remember liking it even as a child.  I even was born under a fire sign.

Who cares, all flames are hot.\n\n"The color and temperature of a flame are dependent on the type of fuel involved in the combustion."

Hi there,\n\nTemperature vs colour goes red, orange, yellow, green, blue, violet. It is simply the spectrum of light (think rainbow) because that is what it is based on.\n\nSo red light is actually the coolest, and as you go up the temperature scale, you run through the spectrum to violet.\n\nWhite light is a combination of ALL the different colours of light, so something which glows white hot is just releasing all different levels of energy, so it appears white. So in actual fact, blue (or more accurately violet) is hotter, because if something is blue hot, then it is releasing ALL really high levels of energy, but you rarely get anything which is completely blue hot - there is almost always some sort of mixture, and usually, the object glows white tinged with blue (which just means that the object is releasing all different levels of energy, but predominantly or mostly blue!)\n\nJust for your interest, the way this works is, when you heat something up, you are exposing it to invisible energy called "infra red" which is just heat. So when you touch something and it feels hot, you are simply sensing infra red energy!\nThis energy is "weaker" than light (so light is actually more energetic than heat), but if you let an object get hot enough, it stops being able to release the heat as just infra red and starts to release it as visible light. The hotter the object gets, the further along the spectrum is the light emitted.\nActually, if the object absorbs enough energy it will start to release Ultra Violet (UV) and X-Rays!
