The Rainbow Masonry Designer App is an iPad application that allows architects to collaborate in real time with building owners and construction companies to visually select brick facades that reflect a project’s vision. You can view and select colors, pattern/bond, and mortar colors. Once a combination is selected, a PDF can be sent to various brick manufacturers for samples and estimates. By dynamically selecting brick colors, patterns, and one of 60 different Rainbow mortar colors available, much of the guesswork and color speculation can be avoided. Holcim US Inc.
