Current behavior:
For the dark theme, ion-option label text color is #000 (black) and there is no sass variable to override it.
It is possible to override only selected item using $alert-ios-radio-label-text-color-checked which is not enough for the dark theme.

Expected behavior:*
There should be a variable which could be used for overriding ion-option label text color.

Steps to reproduce:

1. Change the background of the Alert:

$alert-ios-background: #24242d;
$alert-md-background-color: #24242d;
$alert-wp-background: #24242d;

2. Create simple select with few options.

<ion-select [(ngModel)]="gaming">
      <ion-option value="nes">NES</ion-option>
      <ion-option value="n64">Nintendo64</ion-option>
      <ion-option value="ps">PlayStation</ion-option>
      <ion-option value="genesis">Sega Genesis</ion-option>
      <ion-option value="saturn">Sega Saturn</ion-option>
      <ion-option value="snes">SNES</ion-option>
</ion-select>

3. Run as a website in browser
4. Click select and check the options label color which is black.

Other information:
There should be such sass variables available:

$alert-ios-radio-label-text-color;
$alert-md-radio-label-text-color;
$alert-wp-radio-label-text-color;
