As you can see every colors are meant to be used for a specific purpose. Of course, if in your case you can't use all the colors do your best to stay as close as possible to the original palette.
Find in this page a table with the exact colors codes in multiple color models (HEX, RGB, HSV, HSL, Lab).
There is also files in the palette/ folder defining the colors in HEX in multiple formats: YAML, CSS, SCSS.
Important: if you implement the color palette in an editor, a website, a service, ... please do not modify the color codes (use the exact ones listed in this page).
If you implement this palette as a color theme somewhere, code comments should be displayed in italics, and keywords should be in bold (to easily identify them).
Rowan is a seventeen (17) color palette but if you need (or are restricted) to only sixteen colors, you can ignore the accent (acc) color or use the numbers (nbr) color for the Diff Inserted texts.
