Dirt development

This shows the progression of how I wanted the dirt to look.

 For instance, the first section shows the base one colour look, which is far too basic and wouldn't suit the overall interaction.

The second and third segments show how I was working with lerpColour and how it wasn't working.

In the bottom line I looked at the different colour progressions. These included gradients so that it seems more natural and realistic.

The first is too light as it detracts from the rest of the interaction and the last is slightly too dark which also takes away from it.

The second segment in the last line is a rich enough colour which I think adds warmth and overall is a positive addition/ accompaniment to the interaction.
