Controlling color with checkbox controller
I was wondering if there was a way to control the color values used with the Fill effect based on whether a checkbox was checked or not. For example if i had a solid with the fill effect applied and I had an adjustment layer with 32 different checkboxes. One checkbox could be named Red, the other Blue and so on. Is there a way depending on which checkbox I check that the color values I assign in the expression become active? In other words multiple instances of if/else?

Sure, here’s a simple example with 5 colors:
L = thisComp.layer("Controls");
if(L.effect("Red")("Checkbox").value)
[1,0,0,1]
else if (L.effect("Green")("Checkbox").value)
[0,1,0,1]
else if (L.effect("Blue")("Checkbox").value)
[0,0,1,1]
else if (L.effect("Yellow")("Checkbox").value)
[1,1,0,1]
else if (L.effect("Orange")("Checkbox").value)
[1,.5,0,1]
else
value;

I realize this is an older post, but I’m attempting to do the same thing. A toggle between two colors. However I can’t figure out the color system this is using. I’ve spent a while looking around online and I can’t find an answer.
Is there a way to do this with a hex code or rgb values?
Thanks.

The color channels are normalized to be between zero and one. You could use 0-255 values like this (example for yellow):
[255,255,0,255]/255

You can also convert hex to this format using this expression that Dan Ebberts and Scott McGee figured out:
txt = “FFFFFF”; //the hex code
hex = parseInt(txt,16);
r = hex >> 16;
g = (hex & 0x00ff00) >> 8;
b = hex & 0xff;
[r/255,g/255,b/255,1] -
Thanks! This worked for me, i was missing dividing it by 255 when i was trying it.
