Abstract: Systems and methods for colorizing an image. In one embodiment, a method for colorizing an image comprises assigning a first color from a first color map to a data point to define a first graphical element, assigning a second color from a perceptual color map to the data point to define a second graphical element, calculating a first luminance for the first graphical element, calculating a second luminance for the second graphical element, adjusting a brightness associated with the first graphical element until the first luminance and the second luminance match within a first predetermined range, and adjusting a saturation associated with the first graphical element until the first luminance and the second luminance match within a second predetermined range.
