What People Are Saying

I just wanted to let you know how much I enjoyed your book. It has helped me so much to give a structure to understand how to choose paint. Reading your books was such an "aha" moment for me. Thank you.

This is an amazing group of huge chips that are also labeled with their undertones. It is a must for anyone doing exterior colors and a bonus for interiors.

I love all the choices with justification. Maria's interior consult is SO much more information and material than I was expecting! Such great direction for our new build.

I am very happy with my kitchen and the best decision I made in the whole remodeling process was getting the help of Maria and her team, I am grateful for your guidance every day.
