News December 2024: Petrel/DUG .alut colour maps have been corrected are available in the download section This website presents a collection of perceptually uniform colour maps.

They may also have points of locally high colour contrast leading to the perception of false anomalies in your data when there are none. The colour maps shown above are rendered on a test image consisting of a sine wave superimposed on a ramp function. The amplitude of the sine wave is progressively reduced to zero at the bottom of the image. What we should see is the sine wave uniformly visible across the image from left to right. We also want the contrast level, the distance down the image, at which the sine wave remains discernible to be uniform across the image. At the top of the test image the sine wave height
