brown
Red + Green = black, grey or brown depending on the formula of the colours and the proportions in which they are mixed.
When red and green light are combined, the resulting color is yellow. This is because red and green light stimulate the cones in our eyes to create the perception of yellow.
When green and red are mixed together, the resulting color is yellow. This is because red and green are primary colors that create a secondary color, yellow, when blended.
There is no way to make a red item green by combining another color with it. Because the color green is a complimentary color of red, the resulting color will always be a shade of brown. If you must make a red color green, then you must paint over the color with opaque pigments.
yellow
When green and red are mixed together, the resulting color is usually brown or a shade of gray, depending on the proportions of each color.
When green light is mixed with red light, the colors combine and form black. This is known as subtractive color mixing, where red light subtracts the green color from the green shirt, resulting in it appearing black under red light.
Mixing red and green together will typically produce a shade of brown. The resulting color will depend on the specific shades of red and green being mixed.
When you mix red and blue, you get magenta. When you shine a green light on magenta, the green light will be absorbed by the magenta, resulting in a dark color or black, depending on the intensity of the green light.
There are to possible answers to this question... If what you are mixing is light (like the TV/Monitors does)... or if what you are mixing pigments (like inks, crayons, etc)... In the case of light, Red Light and Green Light will give you Yellow Light... (for example when you are working with the RGB system you have to look at it like this... this is called Additive Colors) In the case of inks, (for example the CMYK color model, that will be called Subtractive Colors) The resulting color will be a shade of brown.
No, mixing green and gold will not give you an orange color. Orange is the combination of red and yellow, with the absence of blue. Since green contains blue, and neither color contains red, the resulting color will be a green.
If light has no red or blue, you would see the color green. Green is a combination of yellow and blue wavelengths, and when there is no red or blue light present, the resulting color perceived by the eye is green.
In red light, a green apple would appear dark or black because red light contains wavelengths that are opposite to green on the color spectrum. This causes green objects to absorb the red light and reflect very little, resulting in a dark appearance.
