Android CheckBox colour not changing

I have a CheckBox and I don't know how to change its colours. I tried creating a custom style in styles.xml and styles21.xml I added there:

<style name="checkBoxStyle" parent="Base.Theme.AppCompat">
    <item name="colorAccent">@color/white100</item>
    <item name="android:textColorSecondary">@color/white87</item>
</style>

then I added the style to my CheckBox, as:

@style/checkBoxStyle

No change in the colour. Its still black and I want it white. Tried creating another checkbox, cuz I taught I might have messed the previous one. Same result.
