White Light is made of all the colours of the spectrum (rainbow).
If we look at something, say, green (like grass) it looks green to us because the chlorophyll in the leaves absorbs all the sunlight that lands on it with the exception of green light which it reflects. Therefore this green light that reflects into our eyes makes us see the grass as green.
White objects, however, absorb no light and reflect all the colours back to us. As all the colours together make white light, we see the object (in your case, a T shirt) as white.
Green light - Green, White light - Green, Red light - Black
While the ball would still be green it will appear black. Anything green absorbed all colours except green. The green light is reflected to your eyes which makes it look green. Thus in red light (with no green in it) the red will be absorbed and no green light can be reflected to your eyes so the ball will look black.
Each piece of clothing usually reflect only a few colours. Pure white light contains all of the colours, so an item of clothing can reflect all of the few colours it is capable of reflecting. If an item of clothing is viewed in magenta light (which is mainly blue and red) then that clothing may show that it is only able to reflect some shades of red and/or some shades of blue.
All colors of visible light are being reflected by a white shirt when viewed in white light. White is the combination of all colors in the visible spectrum, so when white light hits the shirt, all colors are reflected back to your eyes, giving it the appearance of being white.
A white shirt will appear green under a green disco light because objects reflect the light projected onto them. Since the shirt is white, it will reflect the green light predominantly, giving it a green appearance.

Magenta coloured light makes white light when mixed with green light
Green and white
Light green.

If an object is white in sunlight it will be green in green light. A white object reflects all wavelengths (colors) of light that shine on it. If only green light shines on it, that color will be reflected and the object will look green.
Green and white will make a lighter shade of green when mixed together. The amount of white used will determine how light or pastel the resulting green will be.
No you will get White light. no you wont ..you will get a light green colour..
