Here’s what I’ve been playing with and you may or may not prefer this technique. I use a high res texture from Riot Gear and keep it big enough to move around in. I color correct > curves to a dark red, add a new solid and subtract an ellipse mask and feather it out to pop the texture a little. Keep this 2D so it’s always affecting the frame. Then put my one text layer in the bottom corner, my other in the top. Truck across with camera parented to null and do a little rotation style animation on the text itself. Then to get the color change just keyframe the curves on the texture, change it to a green, and as you truck it will switch over. Key the opacities on the text too. And it just takes some playing with. That seems to do the trick, let me know your thoughts.
