Okay i had this when using the 1995 mod. What you do is make sure that you do not use true black or true any other colour. Select the colour you want and then adjust the colours in the small number sections to +1 or -1 (under the colour palette thing) which will fundamentally give you the same colour however it will work
I am not sitting at my comp at the mo so i will only say that i think the small boxes are under the pallete they may not be however yet you cannot miss them. They are three boxes i think made of the primary colours that make up you colour that you have selected? Hope you understand this
