274
<p>The Gamut pattern creates a checkerboard pattern of colors at the
216
275
edge of the YCbCr gamut and nearby colors that are out of gamut.
217
276
The pattern is divided into 4 regions: black, white, red, and blue.
218
277
After conversion to RGB, the out-of-gamut colors should be converted
219
278
to the same value as their in-gamut neighbors.  If the checkerboard
220
279
pattern is still visible after conversion, this indicates a faulty
221
280
conversion.  Image manipulation, such as adjusting contrast or
222
 
brightness, can also cause the pattern to be visible.

<p>The Zone Plate pattern is based on BBC R&amp;D Report 1978/23, and can
