CLCs are oils which are soluble in other oils and esters, but not soluble in water and propylene glycol

Standard single color CLC mixtures have been developed, reflecting, respectively, red, green and blue light. These have clearing points between 50-55°C (122-131°F). Mixtures showing orange and violet are also available, as is a special "silver" mixture which reflects light in the IR region.

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.)
