This particular project shows just how influential colour and design are to an architectural and liturgical space, for one of the very first things that jumps out at you as you compare the before and after states is have the space has moved from an architecturally impressive yet monochromatic space, to one which has come to life with colour -- colour which further accentuates the architectural form.
You might wonder if stained glass windows were added behind the altar and ciborium, but this in fact is a painted triptych made to emulate the artistic effect of stained glass. Canning Liturgical Arts speaks of it accordingly:
An interesting challenge was the creation of a triptych for the back wall of the sanctuary that would simulate stained glass windows. Using a variety of gilding, transparent glazes, and metallic paint, our final product illuminates the sanctuary adding visual interest for the congregation and a majestic backdrop to the baldacchino.
