I had decided to travel light so only had my A350, a macro lens and a monopod, which meant I had to crank up the ISO more than was ideal.
The rock had only the hint of colour but I knew what a few tweaks on the computer would produce. The danger is to over saturate and you can judge whether I have but some of the colour may be due to the industrial pollution seeping through the porous rock.

It's all very well having a macro lens but I will have to have to develop a great deal more patience if I am to use it effectively and pick a location less awkward and slippery than here.
