The current, eighth series of banknotes was designed by around the theme of the arts and released starting in 1995. In addition to its new vertical design, this series was different from the previous one on several counts. Probably the most important difference from a practical point of view was that the seldom-used 500-franc note was replaced by a new 200-franc note; this new note has indeed proved more successful than the old 500-franc note. The base colours of the new notes were kept similar to the old ones, except that the 20-franc note was changed from blue to red to prevent a frequent confusion with the 100-franc note, and that the 10-franc note was changed from red to yellow. The size of the notes was changed as well, with all notes from the eighth series having the same height (74 mm), while the widths were changed as well, still increasing with the value of the notes. The new series contains many more security features than the previous one; many of them are now visibly displayed and have been widely advertised, in contrast with the previous series for which most of the features were kept secret.
