	The Universal Waite tarot deck is based on original line drawings for the Rider-Waite-Smith tarot deck by Pamela Colman Smith. It is not known whether the flat colours used in the standard Rider-Waite were Smith's idea or her publisher's, especially since the Original Rider-Waite Tarot, a facsimile edition of the deck as it first appeared in 1910, shows slightly deeper, richer colours.
