GAMMA(6D)GAMMA(6D)NAMEgamma - get or set the system gamma value
SYNOPSIS
/usr/sbin/gamma [newgamma]
DESCRIPTIONgamma with no arguments prints the current gamma correction value. gamma
followed by a floating point argument sets the gamma correction value.
This system resource can only be changed by the super user. Positive
numbers less than 20.0 are allowable values for gamma. On systems with
gamma hardware, the X server should be terminated and restarted. This
can be done via kill(1) or, if xdm(1) is used, by changing the
terminateServer entry in /usr/lib/X11/xdm/xdm-config to True. Colors in
X clients may not look correct until the server is restarted.

have gamma hardware.
