At one of my recent wedding the florist dyed the orchids a deep indigo color. It gave the flowers a really exotic look, they almost appeared to glow.  The dying technique used was to put the dye into water and allow the stems to drink up the color.  The effect caused was a very natural look of color variation, the center of the flower was a light blue and then gradually increased to a deep purple at the edges of the petals. The picture attached doesn’t really do it justice. For any bride looking for a unique and eye catching effect this is a great idea to consider.
