Oh man I did the exact same thing with soy sauce. Thought I was being fancy adding a splash to everything but really I was just making it taste like salt water. Once I cut back and let the actual ingredients come through it was a whole different ballgame. Lemon juice really is the secret, it brightens everything up without needing to reach for the shaker.

I haven't used them personally but a friend did and said they were fair. Probably worth getting a quote.

Property values might actually take a hit from colors that are too wild. Buyers can be turned off by a house that looks really out of place on the block. Keeping resale in mind is a good idea, even if the current owner loves the color.
