If you're in the middle of a paint project and you start to experience bleed-through, here are a few tips and suggestions to try: Stop painting and let your piece dry completely. Apply 1-2 coats of Dewaxed Shellac or BIN Shellac Based Primer over the bleed-through. Let it dry completely.
Primer by itself will not prevent the stain from travelling up the paint. You need a primer with a sealer and stain blocker. This gives it a non mixing medium that the stain cant mix with, thus preventing bleed through. Do a light sand and use the stain blocker primer that should do the trick.
The best product on the market (in our opinion) to help prevent bleed through on your paint job, is Zinsser BIN primer with ``Synthetic Shellac''. You can find it HERE.
Spray the spots that are bleeding, lightly sand them and then apply an even coat of paint, ideally to the whole wall, though you can do the spot and feather the paint out from there...the potential drawback is you may get flashing on the paint if you don't do the whole wall.
The problem could be with the paint you are using. It could be defective, old, or a low quality paint that doesn't cover well. Another option is to try priming an inconspicuous spot, let it dry, then paint over it to see if that helps. If so, go back and prime all the walls with a stain blocking primer.
Painting a transparent color on top of a lighter layer can really help it pop. Additionally, you can paint over the transparent color a few times to increase the opacity even if it's on a darker background.

Solution. Generally, the problem can be eliminated by employing a suitable solvent based primer or sealer to seal the affected area, prior to repainting the entire surface with the specified original paint system. Tests should be conducted to determine a suitable primer or sealer.

Vinegar and oxygen-based bleach are effective solutions for tackling color bleed on clothes. They work well to restore fabric dyed unintentionally without causing further damage. Mix white vinegar with an equal part of water to create a solution capable of reversing color bleed.
But a few days later, you notice brown or yellow spots starting to appear through your paint job. This is called tannin bleed. Sometimes referred to as “wood bleed,”or “bleed through,” tannin bleed happens when the tannins present in wood migrate to the surface, leading to stains and discoloration of the paint film.
To use vinegar to remove colour bleed, add 1 cup of white vinegar to your laundry load and run through a normal cycle. If the bleeding has not stopped after one cycle, try adding another cup of vinegar to the load and running it again.
Water is actually what's causing the bleed-through in the first place. Water makes the surface of your project wet and activates dyes and tannins. One of the few water-based primers we recommend is General Finishes Stain Blocker.
No, you should not put oil-based stains over latex-painted wood. Oil-based stains do not adhere well to latex paint and can cause the paint to peel. For the best result, use a gel stain that is designed to adhere to painted surfaces and can provide good results without the need for stripping.
Ice. Applying ice to a wound will constrict the blood vessels, allowing a clot to form more quickly and stop the bleeding. The best way to do this is to wrap ice in a clean, dry cloth and place it on the wound.
Amongst substances likely to cause bleeding are bituminous coatings and residues, some dyestuff and lake pigments, metallic inks used on wallcoverings, tobacco tar deposits and resinous materials in timber. Stained areas resulting from burst pipes or overflows may also 'bleed'.

I don't know what brand you use, but if your paints appear translucent on the canvas, it may be due to the paint having more filler and less pigment. The exact ratio of pigment to filler can vary from brand to brand, but in general the Artist Quality paints will have more pigment than the Student Quality paints.
