Buff (colour) Buff (colour) Buff is the pale orange-brown colour of the undyed leather of several animals. As an RYB quaternary colour, it is the colour produced by an equal mix of the tertiary colours citron and russet. The first recorded use of the word "buff" to describe a colour was in "The London Gazette" of 1686, describing a uniform to be "...a Red Coat with a Buff-colour'd lining". It referred to the colour of undyed buffalo leather, such as soldiers wore as some protection: an eyewitness to the death in the Battle of Edgehill (1642) of Sir Edmund Verney noted "he
Single colour reflectometry Single colour reflectometry Single colour reflectometry (SCORE), formerly known as imaging Reflectometric Interferometry (iRIf) and 1-lambda Reflectometry, is a physical method based on interference of monochromatic light at thin films, which is used to investigate (bio-)molecular interactions. The obtained binding curves using SCORE provide detailed information on kinetics and thermodynamics of the observed interaction(s) as well as on concentrations of the used analytes. These data can be relevant for pharmaceutical screening and drug design, biosensors and other biomedical applications, diagnostics, and cell-based assays. The underlying principle corresponds to that of the Fabry-Pérot interferometer, which is also the underlying principle for
