I know this is a FAQ, but none of the other posts have the answer im looking for. I was wondering how to change the color of the text as follows:

lets say that this is what the program displayed:

this is blue //in a blue color
this is darker blue //guess what? a darker blue color
this is red //i think you can figure this out by yourself...
this is darker red
this is standard white
this is green
this is darker green

I have read the other posts on this and they all suggest an alternative approach that i found to be very un-reliable (as in the colors would change without me telling the to) and you couldnt switch the color back to white... Is this possible and how can i do it?
