• - Angle offset: radial offset defaults to 90º (π/2) so first color is at top of circle. 0º would start at 3 o'clock or due east of center.
• - Overlay factor: Blending mode for overlay is atop, and defaults to 0.9. 1.0 seemed to cover too much in one tone close to the center but would be good to expose to the user (almost done already).
• - Output file: currently always takes timestamp and never takes the user supplied output.

Output the colors taken by stepped gradients.

• - Completely rewrite arg parsing based on lessons learned from using structopt
• - Update readme with new examples of radial stepped gradient
• - Write document for functions in radial.rs and linear.rs

Add custom errors, error handling for unwraps and expects

• Write some type of description about the command line arguments and usage, justification/explanation for values chose by default
• Make an FAQ.md or more detailed readme to show usage. Images don't load on doc.rs

• - Specify background color to composite the gradients over.
• - (blocked on palette update and switching to crates version) Flag for WCAG version and only render colors that pass the contrast ratio between itself and the background. Probably good idea for linear too somehow, maybe have swatches only take up 80% of the specified swatch area and background color underneath.

Add rand to generate colors in ranges for

Ability to lock one or two of the parameters and generate random numbers for the other two.

• what would the notation look like for that? (ie. Lch: [30,x,50 to 30,x,y])
