From an online color survey
The code #2B5D34 is the pine of the xkcd color survey. In that project, people online were shown random colors and asked to name them. This deep green is the color most people called pine. It appears in the survey's published list of 954 colors.
Pine or pine green?
Wikipedia has no entry for plain pine. Its list of colors has pine green, #01796F, the color of a Crayola crayon. That one leans toward teal, while this pine is a plain forest green. The list also has a much darker pine green, #2A2F23.
With white text, pine reaches a contrast ratio of 7.73 to 1, so it works well for a dark header. Other greens close to it are hunter green and fern green.
