You can create another gradient to color the text without the use of mix-blend mode:
.container {
width: 200px;
height: 20px;
background: linear-gradient(to right, #43a047 50%, #eee 0);
text-align: center;
}
.text {
background: linear-gradient(to right, white 50%, black 0);
-webkit-background-clip: text;
background-clip: text;
color: transparent;
-webkit-text-fill-color: transparent;
font-weight: bold;
}
<div class="container">
<div class="text">Some text here</div>
</div>
And for better flexibility you can use CSS variable to control the progress:
.container {
width: 200px;
height: 20px;
margin:5px;
background: linear-gradient(to right, #43a047 var(--p,50%), #eee 0);
text-align: center;
}
.text {
background: linear-gradient(to right, white var(--p,50%), black 0);
-webkit-background-clip: text;
background-clip: text;
color: transparent;
-webkit-text-fill-color: transparent;
font-weight: bold;
}
<div class="container" style="--p:80%">
<div class="text">Some text here</div>
</div>
<div class="container" style="--p:20%">
<div class="text">Some text here</div>
</div>
<div class="container">
<div class="text">Some text here</div>
</div>
