### Ionic Framework Version

v7.x

### Current Behavior

When using `ion-select` with `color='secondary'`, the `ion-checkbox` and `ion-item` components inside the `ion-select` still use the default `color='primary'`.

### Expected Behavior

`ion-checkbox` and `ion-item` components inside `ion-select` should inherit the color property defined in the parent ion-select component.

### Steps to Reproduce

1. Change prop `color` of `ion-select` to `secondary`
2. Use with `multiple`
3. Open the options
