from what i understand the BB (any BB) go read HTML, but not write HTML.
also the colour you reply to an email in is the same as the email that came in.
So if the original HTML email was in dark blue, then the reply will be in dark blue.
there is no way to change the default colour.
"That's it then. Cancel the kitchen scraps for lepers and orphans, no more merciful beheadings... and call off Christmas."
