Standard single color CLC mixtures have been developed, reflecting, respectively, red, green and blue light. These have clearing points between 50-55ºC (122-131ºF). Mixtures showing orange and violet are also available, as is a special "silver" mixture which reflects light in the IR region. Product specifications are available for all six standard mixtures at http://www.hallcrest.com
These standard mixtures are all intermixable to give intermediate colors, while keeping the clearing point fixed. (For example, by mixing the red and violet together it is possible to make the orange, green and blue.)
