Random colours from exact colour control colours

Posted by Obed Ampong on July 26, 2023 at 1:41 am

Hi,

Please, I have this expression about random colours but I don’t want it to pick in-between colour. I want to choose just either colour 1, colour 2 or colour 3.

Is there any way out?

Regards

Obed

var color1 = effect(“Color Control”)(“Color”);

var color2 = effect(“Color Control 6”)(“Color”);

var color3 = effect(“Color Control 4”)(“Color”)

random (color1, color2, color3);

Maybe like this:

var color1 = effect("Color Control")("Color");
var color2 = effect("Color Control 6")("Color");
var color3 = effect("Color Control 4")("Color")
var colors = [color1,color2,color3];
var idx = Math.floor(random(colors.length));
colors[idx];

or like this if you want each color to hold longer than 1 frame:

var color1 = effect("Color Control")("Color");
var color2 = effect("Color Control 6")("Color");
var color3 = effect("Color Control 4")("Color")
var colors = [color1,color2,color3];
var nFrames = 5;
var f = timeToFrames(time);
seed = Math.floor(f/nFrames);
seedRandom(seed,true);
var idx = Math.floor(random(colors.length));
colors[idx];
