# Themes for xfce4-terminal and QTerminal

## Install

Per user: 
`make`
System-wide: 
`cp xfce4-terminal/*.theme /usr/share/xfce4/terminal/colorschemes`

## Notes on theme creation

ColorPalette is a semicolon-separated list of hex values (octothorpe included) in ANSI color order:

black;red;green;yellow;blue;magenta;cyan;ltgrey;dkgrey;brred;brgreen;bryellow;brblue;brmagenta;brcyan;white

If ForegroundColor and BackgroundColor aren't specified, the background will be the first color in ColorPalette and the foreground will be the last (typically this results in a dark theme).

If TabActivityColor isn't set, the default of #A00 will be used.

ColorCursorUseDefault (set to FALSE to use the following)
ColorCursorForeground (unsure when this is actually used)
ColorCursor (used to draw the cursor, defaults to ForegroundColor)

ColorSelectionUseDefault (set to FALSE to use the following instead of just inverting text fg/bg)
ColorSelection
ColorSelectionBackground

Hexadecimal color codes can be 48 bit, I don't know if they're just passed to X11 as an `rgb:xx/yy/zz` directly.

## TODO

Create a theme using at least a few of the 12 Bit Rainbow colors or similar methodology:
#817
#a35
#c66
#e94
#ed0
#9d5
#4d8
#2cb
#0bc
#09c
#36b
#639
