Some maps and globes have no lines printed on them at all, for longitude or latitude.
There is no official standard for those that do, but most of the ones I've seen have
had the lines of the coordinate grid printed in black.
"parallels" of latitude
Another name for latitude lines is parallels. These lines run parallel to the equator and are used to measure how far north or south a location is from the equator.
Parallels and meridians. Circles parallel to the Equator (lines running east and west) are parallels of latitude. They are used to measure degrees of latitude north or south of the Equator. Meridians of longitude are drawn from the North Pole to the South Pole and are at right angles to the Equator.
Lines of latitude are imaginary lines that run parallel to the equator and form part of a grid used to describe where on the earth you are. They are often called parallels.
The imaginary lines that run east and west are called lines of latitude or parallels. They are used to measure how far north or south a location is from the equator, which is the line of 0 degrees latitude.
"parallels" of latitude
Earth's parallels are called lines of latitude. They are imaginary lines that run parallel to the equator and are used to measure the distance north or south of the equator in degrees.
The other name that is used for lines latitude is parallels. The main latitude is the equator which is at zero degrees.
Another name for latitude lines is parallels. These lines run parallel to the equator and are used to measure how far north or south a location is from the equator.

Latitude lines never touch, so they are sometimes called "parallels".
The imaginary lines that run east and west are called lines of latitude or parallels. They are used to measure how far north or south a location is from the equator, which is the line of 0 degrees latitude.
Lines of latitude are called parallels because they run parallel to the equator and never intersect each other. They are always equidistant apart and are used to measure distance from the equator in degrees north or south.
Meridians of constant longitude cross parallels of constant latitude. Parallels of constant latitude cross meridians of constant longitude. At each intersection of a meridian and a parallel, the lines are perpendicular (form 90° angles).
The pattern of parallels and meridians, also known as latitude and longitude, is used to give exact locations on the globe. Parallels refer to lines of latitude that run parallel to the equator, while meridians refer to lines of longitude that run from the North Pole to the South Pole. By combining these coordinates, we can pinpoint any location on Earth.
