It would be yellow. Yellow surfaces only reflect yellow, light makes everything that is white or its own color the color of the light, and bananas are yellow.

Blue and purple light.
If you're asking how a plant would grow under pure yellow light, it's important to consider the specific wavelengths of light that the plant is receiving.
It would not grow well at all since yellow is not the wave length of light that plants use to photosynthesize.
All bacteria, including cocci, are colorless under the microscope unless you use a light filter or a stain. If you use a light filter or a stain then the color depends on which wavelength the filter is for or which type of stain you are using.

White light is made up of equal parts of three primary colours; red, green, and blue (Or RGB). A banana will absorb the blue light, and then all that is left is the red and green. If you mix red and green together, you get a gold-yellow sort of colour, the same colour as a banana.
Why do you call it a "white object" ? Could it be because it looks white under white light ... light composed of every color ? Well then, the object must reflect every color. So it appears to be the color of whatever light you illuminate it with. Yellow under yellow light, etc.
White reflects all colors. Since it is under yellow light, it will reflect the yellow color, making it look yellow.
Red lipstick looks unpleasent under yellow light because yellow light absorbs mist of the red color.
GreenBlack. A banana appears yellow in white light, which is a strong hintthat it reflects only yellow light and absorbs light of all other colors.
I would personally suggest a light yellow color or white, neither would show through.
Blue
Yes, but I highly recommend not actually eating it. Some species of fingerling banana's are indeed red/purple and quite sweet. Very nutritious and fun to eat. See photo: Related Links
Blue appears black under a yellow light. For example if you have a blue car and you put a yellow light on it will appear black due to the absence of color. The light has nothing to reflect back.
In a ripe banana, it is yellow and the outside is pretty much yellow. By unripe do you mean under ripe? If so, the banana is green, hard, and unappealing.In an over ripe banana, the insides are brown, squishy, and disgustingThe outside, too, is black, brown, yellowish, and squishy.
An object that appears yellow under white light will have a tendency to maintain its distinctly yellow appearance when bathed in yellow light.
