When undertaking a commission the easiest way for me to understand a client’s wish is to ask for a ‘mini’ mood board. This can be a small postcard-sized piece of card covered with torn pieces of magazine pictures, snippets of cloth, small cuts of wool and screwed up cotton thread that give me an idea of the colours required. In the past when one customer wanted a scarf to complement her new winter look she gave me a snippet of cloth from the inside seam of her new coat.
However, more recently, the wealth of beautiful photographs on the Internet, has allowed mood boards to be generated very easily on platforms like Pinterest. The advantage of this approach is the ease with which ideas come together. Unfortunately, the downside is that accurate colour portrayal of ‘real-life’ on screen is notoriously unreliable and even the same image across different screens/devices can vary significantly. So, if an accurate tonal range is critical then an old fashioned, mini mood board is still best.
With the light shining through, early medieval stained glass panels photograph well (if not too high up in a window!) and the frequent use of bright reds and blues imparts a recognisable aesthetic. It is such a strong visual form that it was easy for the Victorians to mimic and then extensively develop in their Gothic Revival church windows, and, is probably what springs to mind when most people think of stained glass.
With my Art History hat on my personal preference is for the work of the late-Victorian Christopher Whall particularly his early 20th-century windows. This example panel depicting St Chad dates from 1901-10. It is now in the V&A Museum, London, and is from a collection of stained glass produced for a commission for a new window in the Lady Chapel at Gloucester Cathedral.
