Subject: [AE] Color Control expression link to=20 Colorama?

Would appreciate some = guidance=20 here as I attempt to learn more about expressions.

Can I link the Color = Control=20 expression to the Colorama effect set up on a null layer in AE (CS5.5)? =

I have successfully = setup a=20 single Color Control expression effect on a null layer to change the = stroke=20 colors of 5 animated shape layers on 5 separate layers over video clips = in a=20 1:30 sec sequence.

I can manually key = frame the=20 single Color Control on the null to change the colors of all the shape = layers=20 over time in the sequence.

However instead, I = would like to=20 link the Color Control to cycle through more rapid color shifts on the = shape=20 layers using the Colorama effect.

I have placed a = Colorama effect=20 under the Color Controller effect in the same null layer.

I have = pickwip the=20 Color Control to Colorama keyframed input Phase Shift (0x+0.0 - 0x+350 = over=20 time).

This creates the = following=20 expression:

temp =3D = effect(=93Colorama=94)(=93Phase=20 Shift=94); [temp, temp, temp, temp]

Haven=92t come across = =91temp=92 in the=20 expression list:

http://help.adobe.com/en_US/AfterEffects/9.0/WS38785266= 89cb91655866c1103906c6dea-79f8a.html

Tried placing values = in the=20 expression as this example

temp =3D = effect(=93Colorama=94)(=93Phase=20 Shift=94) [0, 350, 0, 350] results in a green color in the Color Control = and the=20 shapes but does not change the color over time.

So what is the = expression telling=20 me besides messing up this step?

A link to a tutorial = or alternate=20 on animating the Color Control would be appreciated.

Cheers,

Robert Alsop
