Sherwin-Williams. An enhanced formula for Harmony latex paint uses baking soda technology to allow the paint to help reduce unpleasant indoor smells. Formulated without silica, the new formula will stand up to frequent washings, and also offers better hide, durability, and application. Harmony’s zero-VOC formula carries the Sherwin-Williams GreenSure designation, is GreenGuard certified, and is packaged in recycled plastic containers. The maker has also recently upgraded its online Color Visualizer. Users can now upload photos of their own rooms to explore color options, and can rate and read reviews of products to help with purchasing decisions. 800.474.3794. www.sherwin-williams.com.
