Default Themeing xml Question

I've been making my theme for almost a week now and im kind of stuck. the only thing i have left to do is change the text color of the text inside the dialer and the contacts. I've changed the hex colors in the colors xml, values/colors, and values/styles. when i did this in the contacts most of my contacts changed but a lot did not such as the headers like where it says A,B,C and so on.the same thing in my dialer. when i change the colors it doesn't change anything. i was wondering if there was a different xml that needs to be edited that i missed somewhere?

also i want to change the green circle for when you answer the phone and i cannot find that anywhere. is it in a smali or something?
