Corporate 2: Module News Show Pro GK4 ver. 1.6: Text Color Silver

Here is my setting for this module:
Under Basic settings ->
Module suffix : nspNm nspSt color
Module ID : newspro1 ( I do not know what this does)
Hence this module is now having a Green Color theme (my Template Color theme is Green) which I want anyway.
Problem: The color of the text of the title of the first arcle is Silver. I want it White as you cannot see this Silver color against Green background
The color of the body of the rest of the articles is Silver. I want it White as you cannot see this Silver color against Green background.

Is there any settings I need to change in Article Layout / Additional Settings under this mod_news_pro_gk4?
or is this needed to be changed in .css file. In that case, please tell me the .css file I need to change and the codes please.

Sorry I cannot give you the link as this site is being developed under localhost but here is a pic of this module.

Many thanks in advance.

Hi
I guess it is Joomla 1.6?
