Alice blue is a pale tint of azure that was favored by Alice Roosevelt Longworth, daughter of Theodore Roosevelt and which sparked a fashion sensation in the United States.

The hit song "Alice Blue Gown," inspired by Longworth's signature gown, premiered in Harry Tierney's 1919 Broadway musical Irene. The musical was made into a film in 1940 starring Anna Neagle and Ray Milland.

The color is specified by the United States Navy for use in insignia and trim on vessels named for Theodore Roosevelt. "AliceBlue" is also one of the original 1987 X11 color names which became the basis for color description in web authoring. The name "Alice Blue" was trademarked in 2001 by a costume company called "Alice Blue Fancy Dress & Costume" in the U.K. but the livery color chosen by them was not the correct Alice Blue shade, but instead a rich royal blue.

This particular shade of blue is also referred as white-blue (or blue-white) and ice/icy blue, due to its very pale coloration.
