Matarial ui theming tablecell text color variants - material-ui

Question

I have a table with information.
The text color of the row depends on a error level.
Now a separate function is used to define the text color. How can this be done with Material UI theming?
The function to determine the text color:
function getColor(priority: MessagePriority) {
if (priority <= InfoPriority.error) {
return 'red';
}
if (priority <= InfoPriority.notice) {
return 'orange';
}
return 'black';
}
snippet of code where the table is defined:
<div
style={{
right: '0',
top: '35px',
left: '1px',
position: 'absolute',
}}
>
<Table stickyHeader size="small" aria-label="sticky table">
<TableHead>
<TableRow>
<TableCell variant="head">Level</TableCell>
<TableCell variant="head">Summary</TableCell>
</TableRow>
</TableHead>
<TableBody ref={body}>
{information.map((item, index) => (
<TableRow
key={index}
sx={{ '&:last-child td, &:last-child th': { border: 0 } }}
>
<TableCell
style={{
margin: '0',
color: getColor(item.priority),
}}
>
{ InformationPriority[item.priority]}
</TableCell>
<TableCell
style={{
margin: '0',
color: getColor(item.priority),
}}
>
{item.summary}
</TableCell>
</TableRow>
))}
</TableBody>
</Table>
</div>
I thought to use something like theme.palette.error.main in the function , but theme could not be found.
Another option is the define the text color for the when adjusting on level is not possible.
