As we tell everyone that asks us about colors used on a project in a photo, colors you see online are not necessarily as they appear in person. Lighting, gloss level, surrounding colors (review Josef Albers colors studies) and bounced light, light direction (N,S, E, W) if outside windows bring in natural light, photography adjustments and exposures all have an impact on the color you perceive in the photo. If you like the way something looks, use it as inspiration and look at paint swatches in your space (we don't finalize colors without being in the space) - and always put multiple samples on the wall especially whites. This project was completed a few years ago and the Benjamin Moore color specified was 2035-10 in a satin (thus the spread of the reflected white in its surfaces).
