Can i style my ion-radio items

Hi all

I’m making an application using ionic, sass.
So i made an ion-radio list with items that comes from the back-end.
But now I want every item to have another background color. So i used sass to loop over these items. But it is not working. The thing is when I print my items in a < ul >, it is working.

Is it not possible to style the ion-radio tag?

my sass code :


$colors: $seagreen, $yellow, $blue, $red, $green, $purple, $darkPurple,$black;

@for $i from 1 through length($colors) {
  ul:nth-child(#{length($colors)}n+#{$i}) {
    background: lighten(nth($colors, $i), 10%);

Thanks in advance
