Impossible and yet it is.

It would be impossible to build anything that's random, much less a color filter array.

Code up some "random" numbers on your computer and see what you get. That's not even random. That's why its truly referred to as a pseudo-random number generator.

I.e. the person affixing the moniker decides. And Fuji has decided.

Eat some grapes and relax.

Fujifilm keeps reffering to the X-Trans sensor's layout as random. For example:

"The unique random arrangement of the [X-Tran's] colour filter array is also highly effective in enhancing noise separation in high-sensitivity photography."

This is nonsense. Anyone who looks at the X-Trans sensor can see that it is made up of a repeating/ pattern of RGB. In other worse, if you see one unit (pixel) of the sensor, you can "draw" the whole sensor, over and over and over again. If the sensor were truly random, you would not know what the next unit would look like. The X-Trans is not at all random, it just has a different layout than the Bayer pattern.
