| Date | 1894 | 
| Description | Abney writes: 'No definite measurements, as far as I am aware, have been made of the change in colour produced by contrast, except in a small work of my own in which results were given in terms of colour mixtures, and earlier by a brief reference in a work by Rood, in which the change produced was endeavoured to be matched by means of rotating disks.'
