It really depends on the paper, and the source of the color, and what you need the paper for, afterward.  A little more specificity, (well, a lot more, actually,) would allow us to give you a more helpful answer.  'Tho my knee-jerk responce would probably be, that you can get the best results if you just buy the correct type and color of paper for your application.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Hypochlorite, peroxide, etc. are all the usual bleaching agents.


I believe industry uses Cl2O.
Neither flask nor beaker.

When doing work experience in a tissue paper factory a few yearsd back, they used Sodium Hyperchlorate to bleach off cuts of rolls back to white for recycling back into pulp.  Blue was the hardest colour to bleach out - it needed 10 times the amount of bleach to shift the blue dyes than it did for the pinks, yellows and greens.
