I would suggest you do the entry and wall along there at least in the same color family and if you want some variety different hues or tints, and then if you want some pop pick one wall in LR or DR for that. And you can have some accent pieces pick up some of that color to tie it together too.

After living in neutral colors for more than 10 years before buying our house, I couldn't wait to have color on the walls! Lighter shades will make the entry way feel more spacious, and paint chips show the different variety of the same shade so it can make it easier to get compatible variance. Tape some on the walls to see how they appeal to you. Pick the colors you like best!
