I have been thinking about painting this landscape for a little over six years. When I took the reference photo, the rainbow appeared to be shining directly into our neighbourhood, showing us the way home. I liked that : ) The only thing that made me reluctant to tackle it was also one of the things that made me want to paint it in the first place: the out-of-focus raindrops on the car windscreen. I wasn’t sure I could do what I had in mind ~ something representational but not too realistic. I needn’t have worried; the raindrops almost painted themselves (at least they look like raindrops to me). No, it was the painting of the rainbow that was the most difficult thing because I wanted to paint a rainbow that was not too ‘rainbowy’ (i.e. to paint a painterly painted rainbow and not an emoji 🌈 ).
I got there in the end by overlapping layers of translucent rainbow colours, blending the cooler colours with the clouds and sky (which is why some of the colours have almost disappeared), and using subtle lines to suggest reflected and refracted light.
