Colour 1 - a warm yellow ochre
Colour 2 - a darker tone of colour 1
Colour 3 - a cool grey, sorry about the quality of the photo. I hadn't realised it was this bad until after I printed the next colour and then it was too late to retake it.
Colour 4 - Light blue
Colour 5 - light green with some grey mixed in.
Colour 6 - Moving back to warmer tones with a light brown.
Colour 7 - the brown above with some purple grey added.
Colour 8 - darker tone of the previous colour.
Colour 9 - Another dark purple brown to add some texture into the rocks. One more final dark to go.
