What's wrong with lavender? Why does everything have to be a boring tan or grey? You sound like the exact reason I would never buy a house with an HOA.
But this is great...there is a market for homes with HOAs and for homes without HOAs. The reason is clearly because homes that are more cookie cutter with standard features retain their value because there are fewer people on the market who want a lavender house. The HOA is partly responsible for upkeeping the homogeneity by enforcing some of these things, thereby keeping values stable. Depending on the HOA, the board can also be full of people on a power trip, but that's pretty dependent on the geographical area(looks like Florida may not be great) and case by case basis.
