I adore bold front doors (If you do the aqua door, make sure to get some orange or coral accents to compliment it. glazed ceramic pots, or flowers in those colors, along w/the bright chartreuse and spring greens, look amazing against all the white.
if you can find some Atomic accents like this doorknob, it would be great! (Retro Renovation)

as for the tiles, what do you mean? how they get installed? or what to install?
what does your entry look like? what do your doors look like?
what kind of tile do you plan on doing?
