Lactophenol Cotton Blue Stain is formulated with lactophenol, which serves as a mounting fluid, and cotton blue. Organisms suspended in the stain are killed due to the presence of phenol. The high concentration of the phenol deactivates lytic cellular enzymes thus the cells do not lyse. Cotton blue is an acid dye that stains the chitin present in the cell walls of fungi.

Methylene blue is generally used as a nuclear stain. Lactophenol cotton blue is used as a stain for fungi.
Trypan blue is used as a vital dye to stain living cells.
Toluidine blue is used in special staining procedures.

There is a stain called "Toluidine blue." From Robert Gilmore McKinnell's book: CLONING of Frogs, Mice, and Other Animals
ISBN: 0-8166-1360-5
page 35: (".... These investigators treated sperm with toluidine blue, a dye that has an affinity for nuclei. It will stain the nucleus of a sperm, inactivating the hereditary material of the sperm without doing much damage to the sperm's motility or its capacity to penetrate an egg.")

There are many blue stains. Another one is hematoxylin, which stains the nucleus blue.
