How to randomly change color of characters
Hello,
i want randomly animate the colors of individual characters in a word
and after a few seconds the colors should transform to white.I tried the text animator “hue” with randomize order and seed.
But that has the drawback that i have to use a fill color before. If i use white text the hue setting doesnt apply.
The hue setting is also very limited. If applied it doesnt change all letters. Aprox. 20% keep the fill color.I think i have to apply an expression selector to the fill color. But i dont know how to define?
It would be ideal if i could define a color palette for the random colors.
Thank you very much!

What do you mean by “randomly animate”?

Hello Dan,
the individual characters should change colors randomly over time.
-
This is a screen shot of my amateurish attempt to write the expression.
The code was only copied from an other project.
But miraculously worked half way.
I really dont understand the syntax for expression selectors.

Try this:
text color = white;
Fill animator color = black;
Expression Selector Amount = 50%,50%,50%;
Expression Selector Amount expression:seedRandom(textIndex,true);
w = wiggle(1,50);
linear(time,0,5,w,[0,0,0])Dan

That works!
Thank you very much!Is it also possible to take colors from a palette for the random colors.
Like i have 5 defined colors which rotates randomly at each character? -
If you change the text color to black and the fill color to white, this will give you random colors for each character from a palette:
seedRandom(textIndex,true);
palette = [[100,0,0],[0,100,0],[0,0,100],[0,100,100],[100,0,100],[100,100,0],[100,50,0]];
// [red,blue,green,cyan,magenta,yellow,orange]
idx = Math.floor(random(palette.length));

Thank you very much. That gives me a lot more control for the colors.
How can i rotate/random change the colors for the letters? The color palette should stay the same.
-
dur = .25; // length of time to hold each color
seedRandom(textIndex,true);
seg = Math.floor((time+random(999))/dur);
seedRandom(seg,true);
palette = [[100,0,0],[0,100,0],[0,0,100],[0,100,100],[100,0,100],[100,100,0],[100,50,0]];
// [red,blue,green,cyan,magenta,yellow,orange]
idx = Math.floor(random(palette.length));

Thank you! Exactly what i wanted.
[But i can produce only the basic 6 colors. Doesnt matter which rgb values i enter in the brackets?]`
edit: I can produce rgb colors. It hasn´t worked because i had another effect on the layer. sorry for that! -
Hi Dan,
Does this effect applies to CS6 ? I can’t seem get it work ?
