Having trouble changing text colour that I added to a GIF.

I've just started using X4 for the first time and what I'm trying to do is add text to the last frame of a gif. I got the text in and see where the colour changing tools are but for some reason even if I made everything red, the text colour still comes out completely different. It seems to be matching it to the colour scheme of the GIF itself. I just want to text to be red.

I've attached a picture of what the text looks like in the gif. That colour is what comes out no matter how many times I change everything to red.

How do I get the text colour to just stay red?
