It is a nice shade of blue. In a way, the blue might keep people from reacting to it as a camera and stiffening up or turning away, if you're into street photography for example.
As for lenses, it really depends on what type of photography you are into. I own a Pentax DA 40mm Pancake lens that I really love, it was my most used lens until recently. It's compact size mounted to a K-5 allows me to stash it in a cargo pocket in my pants if I want to wander around town looking for opportunities but don't want to look like "joe tourist." or want to do some street photos without being obvious. Since the K30 is a bit smaller, you could do the same. It takes fantastic pictures and the focal length makes it pretty versatile, and it is f2.8.
I recently purchased a used Pentax-A 50mm f1.8, and it is a great versatile lens, but it's the Depth of Field variability at the widest apertures that really makes me like this lens a lot. It's the lens I'm using this month here on the forums:

As it is, I used the same 18-55 for nearly a year before buying any other lenses, it's a very good lens, and being weather-resistant allow me to take pictures in terrible conditions. As a NatGeo photgrapher once told me "Bad weather makes for good pictures."
I look for ward to seeing your shots, and consider joining the group I linked above. trying to take a picture every day encourages me to try new things.
). I sure fell in love with my Tamron 10-24mm.
