Colorblindness has no permanent cure as of now. But a sort of treatment or workaround is now available in the form of certain special glasses. These glasses change the colors viewed slightly so that the color blind person is able to make out the difference between the different colors. Note that the extent of it effect is dependent on the type of colorblindness.
Update : Comparison of what you see through Oxy-Iso and EnChroma glasses
There was one type of spectacle called Oxy-iso released in 2013, but that was not very effective.
Now, a US based company called Enchroma has released another one which seems to be better than the first one.
Note that they will not work for everyone and also that you may not be able to pass the Isihara test with that(though some people claim a major improvement)
Also, they are very expensive for what its principle is. So, if it works well enough, I'm expecting cheaper variants to be coming in the market soon.
Will Enchoma glasses work for me ?
You can take this particular online color test to find out !

Apparently Enchroma gives more natural colors than Oxy Iso(which is very purple).
