When light hits a red object, that means all visible wavelengths are being absorbed except the frequency red, which is reflected. The red glass is filtering that color.
When you look through a color filter, all the light except the color of the filter is absorbed.
A blue filter on the opposite side of the light source looks blue. But a blue filter on the same side of the light source looks green or red. depending on the angle and intensity of each initial color and the filter, because those colors are being reflected and absorbed while blue is "let through" or trasmitted.

It would be more accurate to say that a white object appears red than to say that a red object appears white. The absence of other colors of light makes the red only object equivalent to the all color object.
