pseudocoloring

[‚süd·ō′kəl·ər·iŋ]
(computer science)
A method of assigning arbitrary colors to the gray levels of a black-and-white image. It is popular in thermography (the imaging of heat), where hotter objects (with high pixel values) are assigned one color (for example, red), and cool objects (with low pixel values) are assigned another color (for example, blue), with other colors assigned to intermediate values.
