Ive painted 3 large plant pots with emulsion, and having gone to varnish them (to waterproof the emulsion) noticed that the varnish (although clear matt bush on) changes the colour significantly - taking them from pale pastel colours to garishly bright - this has not altered even when dry.
Luckely I did small patch tests on the inside of the plant pots so they are not ruined. Any suggestion on a brand (UK) of varnish that wont do this , or other method to protect the paint? The pots are to go outside.

The outside is not the problem. The moisture comes from the soil, the plant, and the water you use.
To keep the paint on you have to seal the inside.
