RFE: taskopen -c
-c as in color

ideally drawn from the active theme in ~/.taskrc, but not using taskwarriors color rules. 
Each field can be mapped to the taskwarrior color.theme, with key=values in .taskopenrc, like 

PROMPT=color.header
HELP=color.footnote
DEBUG=color.debug
LIST_BG=color.alternate
ANNOT=color.recurring
UUID=color.overdue
ID=color.due.today
FILE=color.due
LABEL=color.active
DESC=color.pri.none
PRI=color.pri.H
TAG=color.tagged
DATE=color.blocked
PROJECT=color.project.none

That way task users will be right at home with the taskopen colors, and changing themes in .taskrc will change the colors for taskopen automatically.
