i'm using wella koleston dye (medium red blonde) and welloxon creme developer (the developer designed for it)

i did use the vol 10 developer with the dye, so now i have brassy-ish dark-ish reddy (slightly) blonde hair.. i just want it to be more vibrant and a bit lighter.

i would use the dye with the developer again, except are you saying less dye will be deposited?

ahaa, im kinda confused!!
im gonna do some googling
