If you are talking about an inside wall......
I had the same problem in my basement bathroom. You need to use mildewcide paint. But before you paint you need to completely clean the walls with bleach....just make sure you do so with proper ventilation. If you don't kill the mildew before painting it will come back because it simply gets trapped behind or in the new paint layer. Also, you will probably have to run a dehumidifier in the room on a regular basis.

You do need to increase the ventilation in the room. Mould and mildew remover will shift the black on the walls but needs to be done often ( supermarkets ).Also try putting a moisture trap or small dishes of salt around the room while you sort out the ventilation it will absorb the moisture. If you are a tenant, your local environmental health department may offer advice. My daughter is a housing association tenant and after an inspection, the association has replaced all the air vents and treated all the walls. Clear now for 8 months.

Mildew is a serious problem. Get a contractor, remove all the drywall, increase ventilation and start over. You can't just "whitewash" that stuff away. Mold has very serious health issues. Respiratory infection, asthma, and sometimes even death. Did you see Extreme Makeover Home Edition last month?

If you used emulsion on the wall,and it went black,try oil based undercoat and top coat on the area, that could do the trick. as an alternative, consider a cavity insulation . consult your local builder. He will have encountered that problem before.

you need to treat the problem as it will come back
i have seen people use bleach, then using the sealant for mould/condensation then when it dries you can paint over it
job done

If it is condensation then the only way to cure it is to increase the ventilation in the room.

Sounds like you have mold growing from the moisture. You have to kill the mold first and then prevent it from returning.
Use Kilz as a primer under your paint, but the most important thing is to kill the mold.
