The human eye has three types of cone cells. Each of the three types is most sensitive at a different frequency of light. The three cells have peak sensitivities at approximately red, green, and blue light. Out of these three, red light has the lowest frequency, green is in the middle, and blue has the highest frequency.

White light is composed of all frequencies. When white light strikes an object, the object will absorb some of those frequencies more than others. The frequencies that get reflected back the most are what give the object its color. For example, a yellow object like a banana strongly absorbs blue light, but reflects back red and green light. When only the red and green cone cells in our eyes are stimulated, we perceive it as yellow.

hmmmm... we see different colors because white light has many frequencies.......

light is an electromagnetic radiation. Of all the kind of radiation, only white light is visible to human eyes. some of this adiation is ultraviolet light. We cannot see ultraviolet light because its frequency is beyond our eyes can see.

We see something because light was reflected from this things. we have twolight receptors, the rods which is used for night seeing (its colors are actually black anbd white) and the cones which is used for day seeing (we have three kinds of cones: red, green, yellow) ....

these cones are sensitive to light.... the mixture of these stimulus ispecepted as the secondary colors or tertyiary colors....

If you don't want to .. you can just close your eyes you know ... j/k
The reason for different colors are the frequencies of each reflected light color ... where the highest frequency of light is the red one as I remember ...
