They appear red and absorb all the other colours.
No, using a red light with green and blue filters will not make white light. White light is a combination of all visible colors, so you would need to use all three primary colors (red, green, and blue) together to create white light.
If light reflected from a white shirt passed through a red filter and then a green filter, the shirt would appear black. This is because red and green filters would absorb most of the colors from the white light, leaving very little to pass through. White light contains all colors of the spectrum, so when most of it is absorbed by the filters, the resulting color appears black.
If you pass white light through a blue filter, only the blue wavelengths will pass through, resulting in a blue light. If you then pass this blue light through a red filter, none of the blue light will pass through, and you would not see anything as there would be no red wavelengths to transmit.
When the boy used white light and placed a red filter in front of it, the filter absorbed all the colors of light except red, allowing only red light to pass through. Similarly, when he placed a green filter, it absorbed all colors except green. Since white light is a combination of all colors, the red and green filters absorbed all the light, hence no light reached the screen.
Red or blue. The reason a red filter looks and is red, is because only red light comes through it, and the same can be said about a blue filter allowing only blue light through. Other colors are absorbed by the dyes in the filter. If white light enters a red filter, then red light comes out, and the same goes for blue.

Coloured filters are sheets of plastic used to get colour away from white light. They work by letting some of the spectrum through and absorbing other parts of it. For example a red colour filter lets red light and some orange light pass through- it absorbs all other colours of the spectrum From Little miss me9087
A white object under red light will appear red. This is because white objects reflect all wavelengths of visible light, including red light, while absorbing little to no light. The white object will reflect the red light, giving it a red appearance.
Colors of light that do not pass through filters are absorbed or reflected based on the properties of the filters. For example, a red filter will absorb all colors of light except red, which will be transmitted through. The absorbed colors are converted into heat energy.
The red cellophane absorbs most colors of the white light spectrum except for red, which is transmitted through the cellophane. Therefore, the white light appears red when shining through red cellophane.
