I am trying to modify this expression, which works:<br>
<br>
color1 =3D [204,0,0,255]; // shade of red + alpha<br>
color2 =3D [0,204,0,255]; // shade of green + alpha<br>
r =3D thisComp.layer(&quot;shape&quot;).transform.rotation;<br>
if (r &gt; 0) color2/255 else color1/255<br>
<br>
To this expression, which does not (only the =3D sign in the last line is d=
ifferent):<br>
<br>
color1 =3D [204,0,0,255]; // shade of red + alpha<br>
color2 =3D [0,204,0,255]; // shade of green + alpha<br>
r =3D thisComp.layer(&quot;shape&quot;).transform.rotation;<br>
if (r =3D 0) color2/255 else color1/255<br>
<br>
Any suggestions on how to proceed?<br>
<br>
Thanks,<br>
