When hair has lightened to 6 level exposed underlying pigment color n whet is the correct toner ahas to achieve a neutral color?

When hair has lightened to a level 6, the underlying pigment is typically warm, often showing orange tones. To achieve a neutral color at this level, a toner with a blue-violet base is ideal, as blue neutralizes orange and violet helps counteract any remaining warmth. Using a toner like a blue or ash-based shade can help achieve that desired neutral result.
