I use a lot of pots sunk into the ground, where the pink wouldn't matter at all. Maybe it would repel some of the invading tree roots in my shady oak tree borders. I like to grow cane begonias, but they don't compete with tree roots very well, so the sunken pot method works well.
I dig the pot in far enough that just about an inch or two of the rim is above the ground level, then after planting mulch over the edges of the pots so they don't show at all.
I also have this big urn that (obviously) you can't plant a big, robust plant in it or you'll never get it out. I put a big tapered pot inside it but first fill the bottom 2/3 of the urn with styro blocks, perlite and old potting soil. So the urn is really just a plant stand, but the pot doesn't show at all.
