How to write expression in such case - 12 (slowing random expression)

Question

Hi,I want this random expression to slow so that I can see the color change, I mean 1st color will stay for few seconds (Maybe 2/3 seconds), then the next color will also pause for some time, and then third color same...I want them to stay for few seconds before shifting to the next color. How can I slow it? what  should I write in the expression so that AE can make the color to stay for few seconds. Thank you

I'm not sure which method you're looking for, but if you just want to cycle through the colors, you could do something like this:

holdTime = 2; // hold each color for 2 seconds
a = effect("Color Control")("Color");
b = effect("Color Control 2")("Color");
c = effect("Color Control 3")("Color");
colors = [a,b,c];
idx = Math.floor(time/holdTime)%colors.length;
colors[idx]

but if you want to pick the colors randomly, it would be more like this:

holdTime = 2; // hold each color for 2 seconds
a = effect("Color Control")("Color");
b = effect("Color Control 2")("Color");
c = effect("Color Control 3")("Color");
colors = [a,b,c];
seed = Math.floor(time/holdTime);
seedRandom(seed,true);
idx = Math.floor(random(colors.length));
colors[idx]
