Color Blindness
Color blindness, also know as color vision defects, is the difficulty or inability to tell the difference between some shades of colors. Frustrations for those with color blindness include reading color-coded maps, buying clothing, and traffic lights.

How can you describe the redness of a rose to a person who is colorblind?
You can't. Colorblind people cannot see that color no matter how you try to describe it. They can't see other red things either, so saying "it's like a strawberry or an apple" means nothing either. <= A perfectly shallow responce.
You can use other senses in describing. Yellow, Red, Orange mean heat, they are warm. Although the person can't really discern among them, they can at least try to imagen by using the sensation of warmth.
Besiders i think this question can only be answered only in the form of poetry or sentimental babble for which I am not tallented enough.
The answer to this question is from the medical perspective No. Men do see colors. But I feel this question is being asked no in the strictest definition of Can Men see color but why are men less able to see the difference in colors that most women experience. The difference is in the makeup and percentage of rods and cones. males having a slight increase in rods vs cones. Mes see movement better and have a slight increase in night vision. Women as a contrast have a slight increase in the number of cones the color receptor. Thus the more refined ability to distinguish one color vs another color. These variations are slight and one man may be more color adept that one woman this is just a generalization over a large group.
Color blindness is most often a genetic disorder, but it can be acquired due to illness, eye/brain/nerve damage, or chemicals. People with this condition tend to see a limited range of colors; a rare few may not see colors at all.
The eye is very much like a film camera. There is a lens at the front, and a 'film' at the rear. The 'film' is the inside back wall of the eyeball and is called the retina. This retina consists of millions of light-sensitive cells that convert light into electical signals that flow up the optic nerve (a nerve emerging from the back of the eyeball) into the brain for processing into what we know as vision.
The cells in the retina can be divided into two kinds. Rods (becasue they are shaped like rods!) are sensitive to light and shade and work well in the daytime, but also at night. If you had only rod cells you would see in black and white. However, another kind of cell - cones - exist (again called cones becasue of their shape) in the retina, and these are sensitive to different colors.
Someone with color blindness either has fewer cone cells, or their cone cells are not working as well as they should. As a result they see fine (thanks to the rods) but their color perception is not as good as it should be, depending upon which 'color' cone cells are nor working.
The most common cause of color blindness is confusion between red and green. Very few people are totally color blind (ie they see in black and white only) - most seem to have some color vision but get confused between certain colors. Oh, and for some strange genetic reason, far more men are color blind than women.
Just lie to say that i have been color blind since birth and have never found such a good jargon free answer. Thnaks
True colorblindness is when someone can only see black, white, and shades of grey. Colorblindness is actually a misconception and is better explained by using the term color vision deficiency. True colorblindness is very rare but color vision deficiencies effects approximately 1 in every 10 men. 99% of the men who are diagnosed as being colorblind are what is known as red/green color deficient.

How do you tell what someones favorite color is?
One way to tell might be if they wear clothes of certain colors most of the time or just simply ask them.
Is the color black a natural color?
Technically speaking, black is not a color at all. Color is the way we perceive light of a given frequency; if it has a wavelength that is, say, 510 nanometers, then we perceive green light. Black, however, is an absence of light. Therefore, black is not a color at all, rather, it is an absence of color. Unless you are speaking of subtractive colors - then black is the presence of all color and white is the absence of all color. Additive color is light - subtractive color is the color that light bouncing from an object creates.
What are three examples of camouflage?
Three good examples of crypsis are:
The leaf tailed gecko (Uroplatus),
Peacock Flounder (Bothus mancus), and
Army Camouflage.
Yes, it does. But it's often done the wrong way: with red, yellow, and blue as the primary colors and orange, green, and purple as the secondary ones. In reality, the primary pigments are yellow, cyan, and magenta and red, green, and blue as the secondary colors. Magenta + Yellow = Red Yellow + Cyan = Green Cyan + Magenta = Blue
