Here's a place to start: Sails and Rigging.
These represent 4 examples of general color pallets and illustrative styles for sails. It is NOT all inclusive of what's been done on Shipbucket.
There are also a few bare masted examples and a few with billowing sails. There are also several additional sail colors available.
They are organized by complexity.
I'll comment only on my work: USS Constitution and why I chose the colors I did.
Each color was chosen to represent: a general function, a general rope thickness, and to give a general representation of real world color. Function was broadly lumped into categories like
standing rigging,
running rigging, sail cloth, sail panel seams, etc. I also considered time period (natural materials VS modern synthetics and in the 1800's the advances in fabric production)*
* For fun I currently restore 1800's era railroad equipment, for a time I volunteered at the San Francisco Maritime Museum, and other silly things so dabbling in industrial archeology one gets a feel for this stuff.
So, up for discussion might be some ideas on creating some sort of uniformity on how we illustrate rigging and sails.
How much freedom should we allow for sails?
No limits?
Specific color pallets? Or several?
Filled with wind or as drawn in period sail diagrams?
Do we want to dictate rigging colors?
By function?
By apparent rope thickness?
A combo or not at all?
