Changing Color of Text Added Through Expression

[brandonb96942845]

I'm hoping that the masses here can help me solve a problem.

Here's the super-condensed version: I've got a counter on an AE layer parented to a slider effect, and I've added text to it before and after with an expression (I think it's one of Dan's expressions; TextBefore and TextAfter, and at the end it's literally just TextBefore+s+TextAfter).

So what I'm looking for is a way to set the text color for TextBefore and TextAfter, either when the variables are defined or in the equation at the end. The color for TextBefore and TextAfter that I'd like is 255x192x0/FFC000; the color for the slider value I'd like is 255x255x255/FFFFFF.

I've searched all over and I can't find how to do this. Help please???

Try to share the full expression you're using so we can help you better, anyway, you can check this helpful link where you can see all the expression you can use to set a fill color for your text https://helpx.adobe.com/after-effects/using/expressions-text-properties.html

Here's the expression (it's on the Source Text property of the text layer if that makes a difference):

countTotal=100;
textBefore = "Total Space Used: ";
textAfter = " GB";
n="" + Math.round(effect("Slider Control")("Slider")*countTotal/100);
s="";
for(i=0, l=n.length; i<l; i++){
if(s && s!="-" && (l-i)%3 ==0)
s+=",";
s += n[i];
}
textBefore+s+textAfter;

I've already gotten the Slider effect set up the way I need it to display (whole numbers only, no decimal places), and I've got the expression set up to make it read like this: "Total Space Used: 55 GB" (slider changes the number, and the expression is adding the caption and the units). What I'd like is for "Total Space Used" (textbefore) and "GB" to show up as gold, and the "55" (the part parented to the slider) to show up as white.

What do you think--possible?

PS @OussK I glanced at the article, a lot of that is over my head (full disclosure: I'm very much a novice when it comes to expressions and I know I need to get better; the functions on the page you linked that talk about helping keep text properties synched across multiple layers is something I could get a lot of mileage out of, I just don't know enough yet to make them work).
