Need to automatically assign specific colour to text depending on a certain coloured background

[Dan Ebberts]

You could apply a Fill Color animator to your text and then apply an expression like this to the Fill Color property:

color1 = [0, 0, 0.7, 1];
color2 = [.8, 0, 0, 1];

if (thisComp.layer(“BG1”).enabled){
color1;
}else if (thisComp.layer(“BG2”).enabled){
color2;
}else{
value;
}

Add enough colors and “else if” clauses to handle all your background layers. Note that rgba color values range from 0 to 1 so white is [1, 1, 1, 1} and black is [0, 0, 0, 1], etc.

Because all those layers/gradients etc. need the same colors, I would create a color-expression control on a Null, Add Dan’s script to that color-control,
then pick-whip to that color wherever it’s needed.

That way if your colourscheme changes, there’s only one expression to change.

You could also make several colourcontrols and then use an expression to choose between them, that way you’ll have a visual representation of the possible colours in your interface, and you can edit the colour with a colourpicker instead of the 0-1 arrays.

BTW: no need to add a Fill-effect to a text to change it’s colour.
Twirl open your text layer and choose animate->Fill Color->RGB.
You can delete the automatically created Range for this animator, since it will be applied to all characters.
Add your expressions to the colourproperty in that animator.
