I just recently switched over to moar from less and it seems that moar doesn't respect the LESS_TERMCAP standout color settings as less does. My standout color settings are set by:
export LESS_TERMCAP_so=$'\E[01;38;2;187;194;207;48;2;56;122;167m'
This should produce highlighting with a light blue background and white foreground text. However, moar appears to be only inverting the color of the text and background for standout mode.
Per #14 moar should respect LESS_TERMCAP settings in the same way as less.
