Heres my mapwriter.cfg
# Configuration file
####################
# blockcolour
#===================
# each entry should be of the form S:III:D=AARRGGBB
#
# where: III is the block ID as a 3 digit hex number
# D is the optional metadata value
# AA is 2 digit hex number for the alpha channel
# RR is 2 digit hex number for the red channel
# GG is 2 digit hex number for the blue channel
# BB is 2 digit hex number for the green channel
#
# set the alpha channel to ff for opaque blocks.
# if you do not add an alpha value then the block will be
# completely transparent.
#
# some example entries:
# S:002=ffff00ff # to make grass purple
# S:003=80945d32 # to make dirt 50% translucent
# + S:011:2=ff0000ff # to make birch wood blue
