Granger Rainbow (LZW compressed): A synthetic target used to test ICC profiles.
It's a very demanding test, so expect to see some slight posterization/banding,
but not gaping problems or holes. This is an RGB TIFF, no profile embedded.
Use to test both AtoB and BtoA directions.
Lab50.PSD - an RGB image containing all hues and
saturations - all at Lightness=50 in the LAB color model.
An RGB Image Containing All Possible Colors
Here is an 8-bit per channel RGB TIFF image file containing exactly one pixel
of each of the 16,777,216 possible color values. The image is 4096 × 4096
= 16,777,216 pixels, arranged as 256 slices of the RGB color cube. It is
not tagged with any profile. This image may be useful for investigating the
effects that image processing or color transformations have on the number
of colors in an image. http://www.brucelindbloom.com/index.html?RGB16Million.html -
