well, i don't know what to expect ... anyway:

\definefontfeature[quran][arabic][script=arab,colr=yes]

helps to get better arabic, also use \righttoleft instead of the dir 
commands; the ^^ can be avoided with \Uchar"FDFD

in font-ocl you can change this

             local default       = false -- colorvalues[#colorvalues] -- 
or 1 or ... maybe make it an option

so, no default (i used the default as in emoji it was better that way 
and those were the only fonts i had) .. when i have time i'll make it an 
option
