No light will pass through!
The 'red' glass looks red because white light contain a wide variety of frequencies of light letting only the 'red' frequencies through. Which makes the glass under daylight circumstances look red.
If you aim a 'blue' light on it containing only the blue frequencies the glass will absorb them and let nothing through.

"Purple" is wrong, and blue light will not pass through red glass. The red glass will absorb the blue light, therefore no light will be transmitted. You could call that "black", since black is the absence of all light.

Blue and red make purple on the color wheel. So I would have to say purple.

All of them.
If you mean, blue-only light passing *through* a glass that passes only red light, then none.
