I had to go look , because that is news to me.
They have been slowly turning their paints to the new all acrylic tint system, and now regal is becoming Regal Select. RegalŪ Select Premium Interior Paint
Its on the left side on the "for your home" section. 4th product down. They still have it, and theres 2 versions now. New technology and old. Regal Select is low VOC, primer & paint, and uses 100% acrylic colorants. Same application properties.
