What clairol shade can i use over light reddish brown to get rid of the red and be light brown?

To neutralize the red tones in light reddish brown and achieve a light brown shade, you can use Clairol's shades that have a green or ash base, such as "Light Ash Brown" (often labeled with an "A"). This will help counteract the warmth and red undertones. Always do a strand test first to see how the color interacts with your current shade.
