How to change solid color using slider control ?
Hello,
I have a solid layer and I want to change its color using a slider control.
example: (if value = 0, color = yellow //// if value = 1, color = red)
I tried using the below expression that I found in this thread:
slider = Math.floor(effect("Slider Control")("Slider").value);
if (slider == 0)
[.5,.5,.5,1] // medium grey
else if (slider == 1)
[0,1,0,1] // green
else [1,0,0,1] // red
but I am getting an error that the expression result must be of dimension 1, not 4.So how can I do this ?

You need to apply the expression to a color parameter, like that in the Fill effect.

Hey,
Id add two colour controllers to the layer. set one colour to the yellow and the other to red and then write your if else statement but don’t write the 4 value array just pickwhip to the colour controllers.
if(effect(“Slider Control”)(“Slider”)==0)effect(“Color Control” (“Color”)else if(effect(“Slider Control”)(“Slider”)==1)effect(“Color Control 2”)(“Color”)}
hope this helps!
