Multi or Single colored rating stars

I'm developing a web application which is basically using 2(3) colors:

  • Magenta
  • White
  • Grey-scales

The app is a register for local artists and therofre, the users can rate them.

Currently I'm only displaying the reached stars as grey full/half stars.

Now I saw it with some sample rows and it looked like they haven't got a star yet (intuitive: grey = bad).

Do you think I should display all 5 grey stars a background and highlight the achieved ones in magenta?

The theme is overall flat and sterile, so will this be too intrusive?

Because I fear, the bottom of a row will visually dominate the rest, as there are now the rows with the tags and the rating stars.
