-2.  Parsing string input (colours, paths, Etc.)
+1.  Creating an "image specification" (E.G. `BrushSpec`)
+2.  Parsing `string`-based input (colours, paths, Etc.)

 It is worth pointing out two and three reflect the nature of console programs (I.E. text based). Also, I limited the `colourList` and `skiaColourList` as a way to keep things simple. The console does not provide a way for the end-user to look at the colour before confirming it. And, people tend to find remembering "blue" a lot easier than `#068BEC`. Having said that, the main (NuGet) library, allows you to specify your colours using RGB values. So, you can do that if/when you  hook it up to a GUI if you want.
