Issue
The current style is being overridden by the className Mui-disabled
As a result, the color will remain unchanged.

Solution
To address this, override the styles for MuiSlider-thumb or Mui-disabled
One option is to utilize MUI classNames with the nesting selector
"& .MuiSlider-thumb": {
height: 24,
width: 24
}
It's important to note that withStyles attributes correspond to the CSS API. For customizing classNames not exposed by the CSS API, consider using className + style hooks instead.
Full code snippet:
import React from "react";
import Slider from "@material-ui/core/Slider";
import Paper from "@material-ui/core/Paper";
import { withStyles, makeStyles } from "@material-ui/core/styles";
const useStyles = makeStyles(theme => ({
margin: {
margin: theme.spacing(10),
"& .MuiSlider-thumb": {
height: 24,
width: 24
}
}
}));
const CustomSlider = withStyles(theme => ({
disabled: {
color: theme.palette.primary.main
},
thumb: {
// color: "red"
}
}))(Slider);
export default function MyCustomSlider() {
const classes = useStyles();
return (
<div>
<Paper className={classes.margin}>
<CustomSlider
defaultValue={[10, 15]}
min={0}
max={20}
valueLabelDisplay="on"
disabled={true}
/>{" "}
<CustomSlider
defaultValue={[5, 7]}
min={0}
max={20}
valueLabelDisplay="on"
disabled={false}
/>{" "}
</Paper>
</div>
);
}

Update
Incorporating withStyles:
const styles = theme =>
createStyles({
margin: {
margin: theme.spacing(10)
},
thumb: {
"& .MuiSlider-thumb": {
height: 24,
width: 24
}
}
});
function MyCustomSlider(props) {
// const classes = useStyles();
return (
<div>
<Paper className={props.classes.margin}>
<Slider
defaultValue={[10, 15]}
min={0}
max={20}
valueLabelDisplay="on"
disabled={true}
className={props.classes.thumb}
/>{" "}
<Slider
defaultValue={[5, 7]}
min={0}
max={20}
valueLabelDisplay="on"
disabled={false}
/>{" "}
</Paper>
</div>
);
}
export default withStyles(styles)(MyCustomSlider);
