貼給你好了，我找到的，試過，很好使。

在 RichEdit 中實現(xiàn)代碼著色
下面的代碼將以指定顏色對一些指定單詞著色，就象delphi中的代碼編輯器那樣。
procedure CodeColors(Form : TForm;Style : String; RichE : TRichedit;
InVisible : Boolean);

'. ', '/ ', ': ', '; ', '[ ', '] ', '{ ', '} ', ' < ', '> ',
'- ', '= ', '+ ', ' ' ' ', '@ ');
// 保留字...

'case ', 'char ', 'class ', 'const ', 'downto ',
