Grafting growth in the vascular cambium. Occasionally, a so-called "graft hybrid" or more accurately graft chimera can occur where the tissues of the stock continue to grow within the scion. Such a plant can produce flowers and foliage typical of both plants as well as shoots intermediate between the two. The best-known example this is probably +"Laburnocytisus" 'Adamii', a graft hybrid between "Laburnum" and "Cytisus", which originated in a nursery near Paris, France in 1825. This small tree bears yellow flowers typical of "Laburnum anagyroides", purple flowers typical of "Cytisus purpureus" and curious coppery-pink flowers that show characteristics of both "parents".
Colour recovery were made in black and white, using still colour photos and/or some educated guesswork to manually choose a colour palette. Conversely, the goal of colour recovery is to reinstate (as closely as possible) the colour signals of programmes originally made in colour as they were first seen. Colour recovery reconstructs the colour information from actual recovered signals and theoretically without depending on guesswork. As of 2018, colour recovery has successfully been applied to episodes of the BBC TV programmes "Doctor Who", "Dad's Army", and "Are You Being Served?". Due to the well-documented practice of wiping, many original videotape recordings of
