Unfortunately dyeable weapons for any Job aren't available as far as I was aware before level 50 (and even then there's only one or two), it's much later in the game that dyeable weapons start becoming more commonplace I'm sorry to say.

If you can't get one of the dyeable ones at level 50 though, a stop gap I could suggest that would go with a soft pink glamour is the Deus Ex Verbis, as it's a simple book in white with grey and silver decorations. It's not dyeable though, but is simple enough to not clash with other colours.
