Hey, I just got an 03 drift front and have it on my car and right now I am working with paintshop pro, but also have photoshop. Here is my dilemma. The new front I got is yellow primered, and I want to see what it is gonna look like when it is white like the rest of my car but I cant seem to make it white. I can only make it gray..... am I missing something pretty important about the program?

sorry i'm dumb all i have to do after that is adjust brightness.... you can tie me to a log and throw stones at me, I accept my punishment for being a noob
