If you're looking for cheap oops paint check out Habitat for Humanity stores.Good news is they don't tend to chase you. Maybe for a few feet but once you are away from the hive you are no longer a threat. As for protection the only thing I tend to wear is the hat and veil. You really don't need the suit. Or gloves. In fact with gloves you can't really feel what you are doing and will harm more bees that way. Harmed bees give off pheromones that tell the other bees to defend the hive.
Building the hives is really easy. Painting them takes the most time. Any color will do so I just buy the Oops paint from HD or Lowes. Around here darker colors are better. One since people tend to think white=bee hive but not other colors. So vandals are as tempted to knock them over. And since our weather is cooler than say down south the darker colors help to keep the hives warmer year round.
And some wasps will bother honey bees. They are the predators of the insect world. It all depends on the species and how close they are to the hive.
