text colour based on position/index in word
Hi,
I’m trying to write an expression that will make the characters of a word different/specific colours, before changing to white. I think the best approach would be to choose a colour based on its index position, although there may be a simpler way.
I have a version working with the wiggly selector, although I can’t control the colour.
Changing to white is done with a fill colour animator with the range animated, so that doesn’t need to be in the expression.
I could create multiple Fill Color animators but would need to manually select the range for the different letters, which will make editing problematic.
Thanks,

Christian – how you are going to decide “which” words should have that effect?

Hi Christian,
if you start from black text and have a text-animator change the fill to white, you can then control how much R, G and B are affected separately with an expression, the result should be three percentages.
So an expression-selector with result [100,50,25] on a white fill color would change the black letters to a Bright Orange).
This example would make a rainbow:
hue = textIndex/textTotal;
newColor = hslToRgb([hue,01,0.5,1]);
[newColor[0], newColor[1], newColor[2]]*100; -
Sorry for the slow response, I didn’t subscribe to my own question. Lesson learnt, ha.
It’s all the words in a text layer that will be affected. So we don’t need to be selective about which words. We just need to be able to choose specific colours. Sorry if that wasn’t clear in my original post.

Thanks for answering Filip. I’ve tried this expression on text Fill Color text animator, but it has the following error:
Error: ReferenceError: textIndex is not defined.
What am I doing wrong?
Thanks!

textIndex only works for expressions applied to the Amount property of an Expression Selector. Did you maybe not set that up correctly?

Hi Dan, thanks for getting back to me.
I’m sure it’s user error on my part somewhere but the expression is on the Amount property of the Fill Color animator – I’ve attached a screenshot of the expression with the error.

Hi Christian, you need a different kind of selector: remove the “Range selector” and add an “Expression Selector”, then apply the expression there.
An expression on Amount of a range cannot calculate different amounts for different characters/words/lines.

Thanks Filip! It’s getting there. How do I get specify the RGB values? What I need is just four colours that loop – as per the screenshot mock up. The first line is your expression. What I need is the second line, using specific RGB values.
