What wall treatment or paint colors for my small entry should I use?

what colors do you like?what colors are in the room?How is anyone to suggest colors?

I would use a light, neutral paint color with bright trim, like ivory

It really just depends on your personal style,how did you style the rest of the home,what colors were used and such. So you can take the color of the closest room and go up a hue or two so that it is still in the same family. On the other hand if you want a fun wow entrance give it it's own character and start with a favorite color of yours that you have only used in accessories around the house. But don't just stop at the walls add some funky art work a coll shaped mirror stuff like that so that the other rooms can be neutral but the accessories now pop because they share the color of the entrance.

I like when entryways are light and bright.

Lighting will play a big part when choosing for a small entry.I would browse colors charts, look and them in your own home.What others will suggest may not work.
