Description

The Check icon, which indicates a selected option within CustomSelectControl and CustomSelectControlV2, becomes nearly invisible in dark mode due to its dark color. Unlike other elements in the component, it does not adapt properly to the dark theme.

Step-by-step reproduction instructions

1. Open the Storybook documentation for CustomSelectControl from here.
2. Select an option.
3. Confirm, the check icon corresponding to the selected option is nearly visible.
