I went out Tuesday lunchtime to draw and paint this lovely arched DLR station entrance near Mackenzie Walk but once again rain stopped play. Not only that but I realised I was using a non-waterproof pen, (even if it was an ad agency icon, the lauded Sign Pen). Thus it wouldn’t have been any good for watercolouring anyway, even if it hadn’t rained! Thus I brought it back, albeit bespattered with a few raindrops visible here, and scanned it as a black and white (greyscale) image only. Today I finally got round to adding layers of colour digitally, using a limited and muted palette as it was a grey, overcast day. Choosing to drop in colour in a very cut- out fashion on transparent layers, it has a kind of block printing appeal. I was careful not to try and colour in everything too, so it maintained its sketchy freshness. Pentel Sign Pen and digital colour. www.petergander.blogspot.co m
