Kylie M Interiors is fantastic--I just discovered her web page. she describes several elements of choosing paint color I didn't know. I think I'll pick the perfect dark hallway paint (LRV) after learning from her site. Thank you Kylie!
Finally made decisions on the paint colors for the renovations. Gray owl & Chelsea gray (main living space and master bedroom), woodlawn blue (bathrooms) with ceilings and trim simply white. all colors by Benjamin Moore.
