SenseHAT LED-matrix colour depth is only 6 bit

[df2qy]

The LED2472G chip driving the 8x8-LED-matrix supports only 6-bit colour depth, sending values >63 on any colour channel results in no effect or unexpected behaviour.
Right-shifting the colour values by 2 bits before sending them to the senseHAT solves this problem.
I made a workaround and a suggestion for a fix in "Set LEDs.vi", see attached pictures.
