The permissions you see when you ls -l a file are derived from a 4 digit octal number. Ignoring the first digit for the moment (setuid,setgid and the sicky bit) we have 3 octal digits these digits represent the rights of, in order, owner, group and world to the resource. since 8 is the 3rd power of 2 we can represent 3 states with each octal digit (since 4+2+1=7) depending on which values are set (this is a bitmask ie based on powers of 2, handy to manipulate with bitwise operations)
The umask defines the permissions that are NOT available to each user group.
thus a umask of 027 means that owner has all rights, group has read and execute rights and everyone else has no rights.

XmSetColorCalculation(3X)XmSetColorCalculation(3X)NAME
XmSetColorCalculation - A function to set the procedure used for default color calculation
SYNOPSIS
#include <Xm/Xm.h>
XmColorProc XmSetColorCalculation (color_proc)
XmColorProc color_proc;
DESCRIPTION
XmSetColorCalculation sets the procedure to calculate default colors. This procedure is used to calculate the foreground, top shadow, bot-
tom shadow, and select colors on the basis of a given background color. If called with an argument of NULL, it restores the default proce-
dure used to calculate colors. Specifies the procedure to use for color calculation.
Following is a description of the XmColorProc type used by XmSetColorCalculation:
void (*color_proc) (background_color, foreground_color, select_color, top_shadow_color, bottom_shadow_color)
XColor *background_color;
XColor *foreground_color;
XColor *select_color;
XColor *top_shadow_color;
XColor *bottom_shadow_color;
Specifies the procedure used to calculate default colors. The procedure is passed a pointer to an XColor structure representing the back-
ground color. The pixel, red, green, and blue members of this structure are filled in with values that are valid for the current colormap.
The procedure is passed pointers to XColor structures representing the foreground, select, top shadow, and bottom shadow colors to be cal-
culated. The procedure calculates and fills in the red, green, and blue members of these structures. The procedure should not allocate
color cells for any of these colors. Specifies the background color. Specifies the foreground color to be calculated. Specifies the
select color to be calculated. Specifies the top shadow color to be calculated. Specifies the bottom shadow color to be calculated.
RETURN VALUE
Returns the color calculation procedure that was used at the time this routine was called.
