Out of interest can someone tell me what strength the wella pastels developer is? Been through loads of posts no one mentions it's strength. I have obviously looked on the bottle it doesn't state. I want try a wella toner I have bought the illumina 10/69 kp 10/38 and kp 10/16. I like the Goldwell because of the low strength. Thank you in advance. I tried to delete this so not to waste busy peoples time. So have modified. Googled is 3%.
