I believe you would NOT use a red dye.
The dye coloring for chaos axes are inversed, so if you ever get confused, check out Guild Wars Wiki, I'm pretty sure that there is a dye chart there.
Hope that helps,

EDIT: Sorry, I guess I don't know my dye stuff as well as I thought I did. After looking at a dye chart that somebody posted a link to, it looks like green and yellow mixed makes the most bluish blue.
Sorry if I confused you.
