Applying color transform after transition

Thank you for answering all of my previous questions, I am doing a lot of use with FlashEff so I run into issues every now and then.
Now my problem is that I try to set color transform (txt.transform.colorTransform = myColor) on a text field, after this text had a show transition.
It doesn't work. The color isn't changing.

Please help.

It won't work like that. You need to add the colorTransform directly on the FlashEff instance if you already set the target.
