When I look up that hex code, it matches the first picture. Entering the hex code in EB gives me the same result.
However, when I'm editing the header or footer, or have a splash page open, the color is darkened by a mask color. Are you seeing that darker color even in the published / previewed view?
Also, where exactly are you defining the color? On the page's Body Fill setting?
