|Turquoise Edsel watercolour sketch on cotton paper|
Like the experimental vehicle I experimented with this sketch. I can't recall ever trying to paint rust before and I knew it would be harder than it looks. The parts where the rust and the paint mix, is difficult to render. Busting out your dry brush technique is helpful with that. The parts, like the roof, where it's completely covered in rust was a little easier but the little bit of light hitting on it really makes a difference in the way it looks. You think you can just pull out your burnt sienna because it's a fairly rusty colour, but then you realise rust isn't just one flat colour. I ended up using a combination of burnt sienna, brown madder and raw sienna to get the subtle differences. If anyone has any tips on painting rust throw them my way, I have a few more of these old timers I'd like to paint.
