which is an open source profile editor that can produce rough monitor profiles using
subjective tests.
To produce very accurate color profiles, you will need a color target (for input calibration
??”such as scanners and cameras) or a colorimeter (for output calibration??”
such as printers and monitors). Color targets are fairly readily available, but colorimeters
that work with X11-based systems are quite rare. (And, colorimeters are generally
expensive, often costing as much as the monitor or printer being calibrated.)

Core Fonts: Fonts the Old Way
10.1 Old Fonts Versus New Fonts
Once of the main differences between Old X and New X (Section 1.3) is the way that
fonts are handled. The old font system is often called Core Fonts, because it manages
fonts using requests defined in the X core protocols (as opposed to extensions; see
Section 1.15). Fonts are managed by the server, and clients instruct the server when
and where to draw each glyph (character image). The actual font information can
come from files accessible to the server or from a font server, and they may be in any
of several different formats.
The problem with core fonts is that they are monochrome only, meaning they are one
color.
