Try the attached MarkupColorizer class I wrote. It uses a few regex expressions and regular string parsing to analyze the markup string. Span elements are used to format output with color, optionally with Style or CSS Class. There are also some other options like backcolor, font, changing each element color and option to generate only body or full document. I don't think there are many bugs left, note that scripts usually need to be escaped by common practice. Here is a usage example:

Using mc As New MarkupColorizer
    mc.TableColor(MarkupColorizer.Colors.Comment) = Color.SeaGreen 'change a default element color
    mc.DocumentBackColor = Color.LightYellow 'change document backcolor
    mc.UseCSScolor = True 'span class formatting
    Dim encoded As String = mc.Colorize(htmlcontent)

End Using

'htmlcontent' is a string containing original markup, 'encoded' is the returned color encoded document that you may have different uses for.
