I used this paint "off the shelf" as is and painted my walls. It looks great. Did I make a mistake using this as is?

Thank you for your question. Using an un-tinted product can cause an uneven appearance and doesn't always provide a proper hide. All other features of this paint will be included even if used as is. In the future we would recommend even when looking for a white to have them add some pigments to it for proper coverage.
