Consider the following:
const theme = createTheme({ primaryColor: "teal" });
<Title>
<Text c="teal" inherit span>
primary color text
</Text>{" "}
normal color text
</Title>
It seems that --mantine-color-primary-text doesn't exist, so setting c="primary" will do nothing. Is there a way I could color a text in primary color, without hard coding c="teal"?
