Dual SIM: Different text color for different SIM, how to change color?

[litster]

So I have a T-Mobile SIM (SIM slot 1) and an AT&T SIM (SIM slot 2) in my 950XL. In the T-Mobile Messaging app, the text is in blue. In the AT&T Messaging app, the text in purple. I want to change the text color in each app but I haven't found a way to do so. Any suggestion?

Changing your Color in Theme will affect both. SIM 1 should be the chosen accent color and SIM 2 will follow with a complimentary color.

Thanks for the reply. I can change the accent color. Too bad I can't change the complimentary color.
