All that to say our house is getting painted. I will do some rooms myself (I quite enjoy painting) and we will hire someone to do the main parts because I'm not tackling a two-story wall with a vaulted ceiling. I'm crazy but not that crazy.
Because this colour will be carried throughout our house I wanted to be sure I'd like it but didn't want to paint parts of the wall in every room. I saw this idea somewhere but, despite much searching, can't find the original post I saw. I commented on it so if it was your post please let me know.
I narrowed my choices down to five beiges and bought some samples. I then painted each colour on several sheets of white paper, labeled them, and let them dry.
Once the papers were dry I hung them around the house in different locations. As you can see, the lighting totally changes depending on the room. Once they were up we were able to eliminate several right away and then I took a few weeks to narrow down the final three to one.
