Change text color every word

[David Schagerström]

Some stuff has changed. It now needs to change between 3 color like this 1 2 3 2 1 2 3 2 1.
What I’ve tried to do is to I’ve set the text color to color 1. Then added two fill color expressions. the first one has …

textIndex%3 ? 0 : 100

and the second

textIndex%2 ? 0 : 50

But it gets messy after the first 3 word as one would expect. was thinking that I could get solved with an “if” expression, but have no idea how to write it.

Thanks for any help!

I would think one would be like this:

(textIndex-1)%4 == 1 || (textIndex-1)%4 == 3 ? 100 : 0

and the other would be like this:

(textIndex-1)%4 == 2 ? 100 : 0

I managed this by butchering one of Dan’s other posts:

Set text colour to white
Add animator for fill colour RGB – set that colour to black
Add text selector | expression – set amount to 50%,50%,50%

then in that amount add the following expression:

palette = [[0,100,100],[100,0,100],[100,100,0],[0,0,0]];
// [red,blue,green,white]

switch (textIndex%4) {

case 1:
idx = 0;
break;

case 3:
idx = 2;
break;

default:
idx = 1;
}
palette[idx]

Cheers Dan! Works like a charm!
Question, I need to make this a color. This only allows me to change the grey scale. how would i change it to RGB?

Thanks!

Thanks trevor! It seems to work. I just dont understand the color values? are they in RGB? cant change them into what I need.

Cheers!

This is for a Fill color animator with an expression selector, correct? One of the choices is RGB. Or maybe I don’t understand what you’re doing.

Ok I understand now how it works! I was being slow.
Thanks again!

I’ve kind of figured out what is going on… 😉

Adding the fill (RGB) animator allows the change of levels between the ‘text’ colour and the ‘fill’ colour

The ‘range selector’ doesn’t allow for a per word selection, only a range within the whole text box, so we delete that

The ‘expression selector’ allows the change to occur based on the index of text within the text box – with the expression disabled you can see the colours generated by using the ‘amount’ values as R G and B. – i.e. at 100,100,100 it is all ‘fill’ at 0,0,0 it is all ‘text’ colour

It’s less confusing if the text colour is Black and the Fill is white – thus the amount values become RGB rather than 1-R, 1-G, 1-B.

With the amount expression enabled the default expression does a gradation between black and white over the text box.

With the expression below the value depends on the index of the word (if ‘words’ is selected for the expression to be based on)

The palette can be changed accordingly

I hope this helps, it certainly helped me to think about it (and thanks to Dan for the original)

palette = [[100,0,0],[0,100,0],[0,0,100],[100,100,100]];
// [red,blue,green,white]

switch (textIndex%4) {

case 1:
idx = 0;
break;

case 3:
idx = 2;
break;

default:
idx = 1;
}
palette[idx]
