as you said in you email. I dont like the front in the translation either
starting for the color. if you wanna chose the same color of the karaoke it would be: &HBDB43E& (bord) and &HFBFFC7& (primary color) also I would use bord1

but I think using just white (without bord) it would be fine as well
and about the front style I have an example here.

dunno if you like it but I do XD
it has white alpha border and I guess you cant use it in the mkv file but I think white without border looks fine too
in the talk part I like all ^^
excepting the line you \pos on top. "Leah-san were you that tense?"
both lines could be on bottom

I like very much the front you've used this time ^^
but I would say the color styles for both hosts should be: both with border or both without border. I know probably the male host has black border but since the background is black too we can't notice it ne? the style for the female host is very good ^^ . So I would try black color with white border or white color with grey border
ken's style using blue and green is a little weird but I like it a lot! ^O^
good job steffi! ^^
