Thank you! That's exactly what I was going to do minus the black. Also I like to create a dark brown with tones of red violet in it on level 6 hair. Would you recommend using dark brown with your warm auburn or the bright red? And would the same rule apply of use black mix in with it? I use redken gels/shades/fusion so I look at your comparison chart often. Matching similar colors are challenging but I like the crystal clear look eco colors gives. Thank you much!
