How To Change Material TextInputLayout OutlinedBox Unfocused Color

I have an OutlinedBox TextInputLayout and I want to change the box color in the unfocused mode of editText.

How can I do that?

In the theme Add colorOnSurface attribute and assign any color you want

<style name="Apptheme"
       parent="Theme.MaterialComponents.Light.NoActionBar">
    <!-- General theme colors -->
    <item name="colorPrimary">@color/material_green_500</item>
    <item name="colorSecondary">@color/material_green_600</item>
    <item name="colorAccent">@color/illiniColorAccent</item>

    <item name="colorOnSurface">@color/blue</item><!--inputtext unfocused color-->
</style>

The result is: Also colorPrimary is the color of focused state.

Other attributes you can customize are:

<item name="enforceMaterialTheme">true</item>
<item name="enforceTextAppearance">true</item>

<item name="boxBackgroundMode">outline</item>
