On my search for brighter reds, Tia Má mentioned she liked to wear Carbono (Colorama) with some red polish (such as Maxi - Colorama - or Doce Orgulho - Risqué) layered on top.
I was not impressed with the result. The lighting in the hotel room didn't help, and I didn't care so much for the colour.
A few days later, I decided to try yet another top coat: Cobertura Fosca da Cor - Efeito Fosco (Colorama). It's a matte finish top coat. I liked the look and the finish, with a new tactile sensation.
The photo is a bit blurry, but it was the only one that captured the matte effect.
