LD Lines is a French shipping company. It is predominantly a freight operator, with both deep-sea and ferry operations, but also operates some passenger services. Its ferry routes are on the English Channel and Mediterranean Sea.

The company is a subsidiary of the Louis Dreyfus Group.

LD Lines' English Channel operations commenced in October 2005, operating between Portsmouth, England and Le Havre, France. This service was introduced following the withdrawal of P&O Ferries' long-standing operation on this route.

Initially there was one sailing per day in each direction, with the Portsmouth-Le Havre sailing taking place overnight. This utilised one vessel, the MS Norman Spirit, which is ironically a former P&O vessel (used on their Dover-Calais route until May 2005). In 2008 the Norman Voyager was introduced on the route, she was withdrawn in September 2009 and chartered to Celtic Link Ferries for service between Cherbourg and Rosslare and Cherbourg and Portsmouth. In November 2009 Norman Spirit was moved to the Dover-Boulogne route, her place was taken by Cote d'Albatre which remained on the route until the Norman Spirits return in 2011.

Color Lines (aka Lines) is a computer puzzle game, invented by Oleg Demin and first introduced as a video game by the Russian company Gamos (Russian: Геймос) in 1992.

The game starts with a 9×9 board with three balls chosen out of seven different colours. The player can move one ball per turn, and the player may only move a ball to a particular place if there is a path (linked set of vertical and horizontal empty cells) between the current position of the ball and the desired destination. The goal is to remove balls by forming lines (horizontal, vertical or diagonal) of at least five balls of the same colour. If the player does form such lines of at least five balls of the same colour, the balls in those lines disappear, and he gains one turn, i.e. he can move another ball. If not, three new balls are added, and the game continues until the board is full.

In 1995 the first Windows version was developed by Igor Nedelko and Andrey Akselrod for the AbrewSoft company as a shareware. This was a faithful remake of Color Lines, with 256-color graphics and a custom window with buttons for all the functions. The characters on the pillars, champion and pretender, were still there, but in a modern office instead of a medieval setting. The figurines to the right was ever so slightly animated, blinking and tapping a hand now and then. The ball with the four cyan arrows was for moving the window around. A new concept of a four-color balls on advanced levels was introduced with this version.
