|Color choice - very tricky.|
I had no idea that only working with four colors could make color choice so difficult. But it is. Each and every one of these quills is an agony of choice. The regions at the edge of bright/dark regions are particularly challenging. How and at what point does the gradation start? Some of the margins were easy, since they were very 'digital' - one side bright and the other dark. But the messy grey regions ... very challenging. I spent a lot of time making decisions between what met my artistic vision, and what was the most scientifically accurate.
One of the greatest challenges was the quilling around Copernicus crater, the larger bright crater on the right side of this image. But I'll talk more about that next time!
