Is there some sort of color you could use that isn't permanent, in case it doesn't suit you?

If you tend to have an ivory or creamy colored skin tone with freckles, burgundy may not work that well (at least it doesn't on me). If you have more pink in your skin burgundy should look great.

Anyway, you may never know unless you try.

ETA: For dimension, try using two shades at once. Run one shade through a part in the roots, then another in the part next to it, and so on. Or alternate the whole head. I do this with brown and blonde and I get very natural looking highlights. Good luck! Post back your results if you can.
2/c and some 3A.
Protein sensitive but can use occasionally
Highly porous. Color over grey.
Best 1st day method: Super Soaker
Stylers: Mix Curls in a Bottle into everything for shine. Terrible pj
Sometimes try roller sets - classic glamor but I prefer my curls.
Every day is a gift
