I'll be coloring my hair tomorrow after a final vitamin c mask, and I'm not sure about color mixture. I use punky color, so it's either mostly yellow, some orangey red, some purple and maybe a touch of black? Or just orange and yellow? Or just orange and purple, or red and blue and yellow added to more yellow??? I've wanted this color for a LONG time and I've achieved a pretty light and almost uniform color for a base, it would be a shame to screw it up at this stage
