Header middle crossing two half columns - bootstrap

I have this layout:

<h1>INFO</h1>

<div class="container-fluid">
    <div class="row">
        <div class="col-lg-6 col-sm-12 bg-blue">
            <div class="bi-left">
                <img src="">
                <ul>
                    <li>text</li>
                    <li>text</li>
                    <li>text</li>
                    <li>text</li>
                </ul>
            </div>
        </div>
        <div class="col-lg-6 col-sm-12">
            <div class="bi-right">
                <img src="">
                <ul>
                    <li>text</li>
                    <li>text</li>
                    <li>text</li>
                    <li>text</li>
                </ul>
            </div>
        </div>
    </div>
</div>

I need my first half column to have blue bg even when columns get repositioned to col-12. And I need my h1 to be right in the middle crossing through half with blue bg to second half with basic white bg.

here you can see what I am trying to explain
