/* Intensities */
* 50% became #6
* 100% became #F
CRT (Cathode Ray Tubes) displays have a non-linear response to input voltages. This non-linearity is approximated by a power function called gamma, with a typical value around 2.2.
This non-linear response of CRTs is the reason why #6 was chosen for the 50% color component instead of #7 to compensate for it.
