The reason is because the color of the object's pigment is reflected to our eyes whereas other colors are absorbed.
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.
It will look black, or green, depending on the hue of the red. A green filter blocks the red light but no red object is reflecting solely in the red wavelengths, and any non-red light will appear green through the filter.
Red - Yellow light is a mixture of red and green light. When a magenta filter is placed in front of it, the filter would allow the red light through, but not the green, making it appear red through the filter. Anyone who listens to 'Anonymous' over me will see I am right when they pick up a set of filters.
The red filter will selectively absorb all colors except red, allowing only red light to pass through. As a result, the white light will appear as red when it passes through the filter.
Paper will appear to be black under a red light because red light has a long wavelength and is less likely to reflect off the white surface of paper.

When the are ripe (red) is the best time to harvest tomato. At the best temperature to kept tomato is 16 Celsius. Don't put tomato in the refrigerator. But the earliest the tomato can be harvest is when a white star appear at the bottom of the tomato. Commercial production do this a lot to ship tomato in all over the country.

Red. As the filter will only allow red light through, it, you can not see anything but reds.
Did you know they actually pay people a lot of money to create names for colors? Tomato red could be any shade of red, as are the tomatoes, depending on the variety of tomato. But I consider tomato red to have a hint of orange.
A red object appears red when viewed through a red filter because the filter absorbs most colors of light except for red, allowing only red light to pass through. This red light is then transmitted to the observer's eye, making the object appear red.
all colors except red will appear black in red light
When you look at a blue object through a red filter, the object will appear darker and possibly black because the red filter blocks out most of the blue light. The red filter only allows red light to pass through, which results in absorbed blue light and altered color perception.
