Luo color by L'oréal lightens the base when put over highlights, but that can be to your advantage to soften the base color so the contrast is reduced. Of course some warmth is released but you shouldn't leave it on longer than 2 to 7 mins. I used P01 with P02 with 25 Vol. to get a bright beige.
If you need a cooler result I would use Dialight which will only deposit when used with 6 Vol. so everything stays ashy on the roots.
