Orange (colour) philosophy of ancient China, orange was the colour of transformation. In China and India, the colour took its name not from the orange fruit, but from saffron, the finest and most expensive dye in Asia. According to Confucianism, existence was governed by the interaction of the male active principle, the "yang", and the female passive principle, the "yin". Yellow was the colour of perfection and nobility; red was the colour of happiness and power. Yellow and red were compared to light and fire, spirituality and sensuality, seemingly opposite but really complementary. Out of the interaction between the two came orange,
Single colour reflectometry which allows time-resolved observation of binding events on the sensor surface without the use of fluorescence or radioactive labels. The SCORE technology is commercialised by Biametrics GmbH, a service provider and instrument manufacturer with headquarters in Tübingen, Germany. 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
