Would this standout enough against black ink if used for grading papers?

Yes, that is what I use it for. It is a more subtle red than red ballpoint ink.

I have an old a.w.faber castell castello 7 fountain pen -do you know if these cartridges will fit this pen?

I am not familiar with the particular vintage fountain pen. But, if the pen accepts standard size cartridges- it probably does- then, this product should work.
