 coloring text based on numbers from an array (list) on Sep 10, 2014 at 7:51:10 pm

So I have the following expression that takes a number from a list and puts it up on the screen every six frames (30 fps). Works great. Now i need compare each number from the list to the following and change the color of the test accordingly:

0-100 - Green
101-140 - Yellow
141 - 160 - Orange
161 - Up - Red

I've tried to use different animator descriptions and changing the hue/saturation, but to no avail.

Any ideas would be greatly appreciated.

Thanks.

```// expression to take input of series of numerical values and display them five per second or every six frames // get our source list listText = thisComp.layer("heart").text.sourceText; // now make an array, assuming a comma delimiter list = listText.split(","); // what's the biggest value? we'll use this as our denominator maximum = Math.max.apply(Math, list); // which number should we look at? one per six frames wholeSeconds = Math.floor(time-inPoint); milliSeconds = Math.floor(((time-inPoint) - wholeSeconds) * 1000); indexModifier = Math.floor(milliSeconds/200); target = (wholeSeconds*5) + indexModifier; // make sure we don't try to find the value-as-a-percentage for an out-of-bounds array number, or try to divide by zero if ((target >= 0) && (target &lt; list.length) && (maximum != 0)) { // this will print to screen the array number or zero speed = list[target]; } else speed= 0;```

Assuming that you're using an RGB fill animator and "n" represents your number, something like this for fill color should work:

``` if (n <= 100) [0,1,0,1] else if (n <= 140) [1,1,0,1] else if (n <= 160) [1,.5,0,1] else [1,0,0,1]; ```

that works good, but returns whatever's between the square brackets... How do I get that number to return and change in the text's color?

Thanks again.

I'm lost. I would only work as part of an expression for Fill Color.
