What does the shade "7.5 Copper Red" actually look like and who is it best suited for?

In professional hair color numbering, 7.5 indicates a level 7 (medium blonde) base with a .5 (copper/mahogany) reflect. On most starting hair colors, this translates to a warm, light-reflective copper-red that reads as a rich auburn rather than a flat red. It works especially well if your natural or current color falls between dark blonde and light brown (levels 5–7), where the pigment can deposit evenly and show its full warmth. On darker hair (level 4 or below), the red tone will be subtler — more of a warm sheen in sunlight — unless you pre-lighten. On very light or bleached hair (level 8+), the copper can turn out intensely vibrant, sometimes bordering on orange-red, so a strand test is strongly advised. This shade is chosen by people who want a noticeable color update that still looks "like hair" rather than a fashion color, and who appreciate a glossy, polished finish over a matte result.
