You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
Her favorite color was BLACK!
White absorbs the least light. The "pigment" that causes the color white does not absorb any other colors, so all the colors are reflected back to you as "everything", or white. Think of white light. There are many colors hidden in white light, and by the process of refraction, white light can be separated and a rainbow of colors revealed. Black, on the other hand, is a pigment that absorbs all colors of light. Since no color is present, what you see is essentially a reflection of "nothing".
That is called a three way switch. It's used in conjunction with another 3 way switch in another area and they both control a light or set of lights. The black is power and the other two are called travelers that wire to the the other 2 gold screws on the other switch. A three way switch can be used as a single pole switch by using the black screw and one of the brass screws. You will have to test the circuit to orient the switch so up is on and down is off, if that is what you desire, because it is not obvious on a three way switch. The green screw is simply your equipment ground. You place your green or bare conductor there.
we will get black color when all the primary colors(RGB)* combine. * R-red; G-green; B-blue the combination of these primary colors in different proportions gives the different shades of colors. when all these colors combine we will get black. Depends on what you are mixing. :-) If you are mixing colored light, then mixing all colors gets you white. If you are mixing paint, it depends on the proportions, but if all are equal, you get black.
In the wall switch box you should have a white and black pair from your source of power (120 volts). The other pair of black and white wires from the wall box should be going to the light fixture junction box. With the power off, connect the two white wires together with a wire nut. Connect the two bare copper ground wires together making sure that at least one of the ground wires goes under the green screw in the switch junction box. Turn the switch to the off position, no little indicator bump showing on the switch toggle lever. Now take the black incoming hot wire and put it under the top screw on the switch. Hot wires always go to the top of switches. Now put the black wire that is going to the light fixture under the bottom screw. Tighten both. Install the switch into the wall box with the switch handle in the down position. All switches when installed must be off in the down position. Install the switch plate cover.
the black wire is the hot wire
Mostly green and black
dark green and white light green and black
White light is made up of all of the colors of the spectrum, so the green looks green because the green light is reflected back to your eyes while the other colors are absorbed. Under a red light, the green light is filtered out so there is no green to reflect so it looks black.
they are red,blue,dark green,light green,white,yellow and black for the frofelers
Dark colors- Black, Dark Blue, Dark Green, Dark Purple....
pastel: blue, pink, yellow, and only sometimes light green.
There is: Black, Silver, White, Pink, Red, Green and light blue.

white is the presence of all colors and black is the absence of all colors, so red, blue and green light mixed together make white, but the amounts have to be equal
The cap is called 'green' because it absorbs all other colors of light, leaving only the green light to bounce from it to your eyes. If no green light shines on it, then there's no light to bounce from it to your eyes, and it appears black. If you only shine blue light on it, then there's no green light shining on it.
An object appears a certain color to you because it reflects that color of light and absorbs other colors of light. For example, a white object appears white because it reflects all colors of visible light (red, orange, yellow, green, blue, indigo, violet). A black object appears black because it absorbs all of these colors--and as a result, none of those colors are reflected back to your eyes. Under white light, the object appears yellow-green because it reflects both yellow and green light and absorbs all other colors. (Remember, white light has all colors of visible light in it). If only green light is present, there's only green light for it to reflect--so it will appear green. If you shined yellow light on it only, it would be yellow. If you shined yellow and green light, it would appear yellow-green again. It you shined red and blue light on it, it would appear black, because it absorbs both of those colors.
