Can use RichText for Harmony OS, you can achieve the same effect. Please see below screenshot for the sample code, which will set Harmony to red.

    Text text = ComponentHelper.getShapeText( context: this); 
    text.setTextSize(80); 
    
    RichTextBuilder builder = new RichTextBuilder); 
    
    TextForm redForm = new TextForm(); 
    redForm.setTextColor(Color.RED.getValue(0);  
    redForm.setTextSize(50); 
    builder.mergeForm(redForm); 
    builder.addText("Harmony"); 
    
    TextForm blackForm = new TextForm(); 
    blackForm.setTextColor (Color.BLACK.getValue ()); 
    blackForm.setTextSize(60); 
    builder.mergeForm(blackForm); 
    builder.addText("OS"); 
    text.setRichText(builder.build());
