| As a side note, it is expected that you would still see your original color underneath the 123. Most primers exist merely to seal and provide a stable surface for the topcoat to adhere to. One of the ways they do this is by skimping on the pigment. It is usually the job of the topcoat to hide, not the primer; so a blotchy look after priming is normal, and no reason to apply more primer.
The sole exception to this is if you are trying to do a Light->Dark color change. In that case, there are specific hiding primers on the market for this use, which are usually tinted grey.
In case you were curious, the surfactants that are likely leaching through your coating are what keep the pigments from separating out of the coating while you are attempting to apply it to the wall.
