What's the difference between cyanine and dye?

Cyanine


Definition:

  • (n.) One of a series of artificial blue or red dyes obtained from quinoline and lepidine and used in calico printing.

Dye


Definition:

  • (v. t.) To stain; to color; to give a new and permanent color to, as by the application of dyestuffs.
  • (n.) Color produced by dyeing.
  • (n.) Material used for dyeing; a dyestuff.
  • (n.) Same as Die, a lot.

Example Sentences:

  • (1) The most successful dyes were phenocyanin TC, gallein, fluorone black, alizarin cyanin BB and alizarin blue S. Celestin blue B with an iron mordant is quite successful if properly handled to prevent gelling of solutions.
