To use colors like MaterialTheme.colors.primary in HtmlText, map simple colors.

HtmlText(
    textId = R.string.hello_world,
    colorMapping = mapOf(Color.Red to MaterialTheme.colors.primary)
)

<resources>
    <string name="hello_world">"Hello <span style="color: red">World</span>"</string>
</resources>

To use string arguments with HtmlText, use CDATA

HtmlText(
    text = stringResource(R.string.hello_world, "Hello")
)

<resources>
    <string name="hello_world"><![CDATA[%1$s World]]></string>
</resources>

You can combine colorMapping with string arguments (CDATA) and all other HTML tags. If you use CDATA, you have to escape double quotes.

<resources>
    <string name="hello_world"><![CDATA[Hello <span style=\"color: red\">World</span>]]></string>
</resources>

Add actual HtmlText library:

dependencies {
    implementation 'de.charlex.compose.material:material-html-text:2.0.0-beta01'
}

or

dependencies {
    implementation 'de.charlex.compose.material3:material3-html-text:2.0.0-beta01'
}

Use it like a normal Text composable

HtmlText(textId = R.string.hello_world)

<resources>
    <string name="hello_world">Hello <b>World</b>. This <i><strike>text</strike>sentence</i> is form<b>att<u>ed</u></b> in simple html. <a href="https://github.com/ch4rl3x/HtmlText">HtmlText</a></string>
</resources>

That's it!
