Which color is used to denote longitude and latitude lines?

Explanation:
Red is used to denote longitude and latitude lines because the graticule—the grid of lines representing coordinates—needs to stand out clearly from other map features. A bright color like red provides high contrast against typical map backgrounds, making it easy to read and use the coordinates at a glance. Since borders are often black, water blue, and vegetation green, red distinguishes the geographic grid without blending into those elements.
