Gray hair dye without red tones

I was born with light brown hair. I mean a light brown without any reddish tones. However, I keep getting gray hairs, so I wanted to dye them, but most brown hair dyes have a reddish tint. I don't want to go black because the gray would stand out even more as my hair grows out... Until now, I've been using the Ash Beige color from the Mise-en-scène Shining Essence hair dye line. But I found out that color was discontinued recently. It was the only gray hair dye available without any reddish tones, sniff sniff. After searching around, I found Ash Brown from Elastin and bought it to try, but the color is too dark. Is there a light brown hair dye that covers gray hair without any reddish tones?
