I Tried the $12 Hair Dye That's All Over Instagram, and the Results Were Red Hot

I mixed in the sections of my hair that I didn't dye with the sections that I did, and this was the end result. As you can see, the red color is really bright and has a rich hue even against my brown hair.

Pro tip: if the color is too bright for you, do a quick wash in the shower after you apply the dye. The color will still be there, but it won't be as bold.
