UMG How to change text color by BP?

In 4.5 UMG it seems there’s the ability to change by code (Bp) the shadow colors but not the text color.
Am I missing something?

UP! How can I change text color from UMG Blueprint?

OK, it was easy. I flagged “Is Variable” on my Text Block Details and I used “Set Color and Opacity” + “MakeSlate Color” nodes on BP for change text color.

I’ve attempted this with no result. The block still remains at the default color, and won’t change. Any help would be amazing.

Figured it out, or at least a workaround. In my version of the UE (4.5) you can’t change the text Colour and Opacity parameters dynamically, by binding a function that does this. However, you can set its opacity to 0 and change the Shadow Colour parameters using a function.

Alternatively, if you still want to have the text and the shadow, you can do this by adding two different Text Blocks and set one of them to Visible (in Details>Behaviour) and the other to Collapsed (it makes the text invisible and not to take space). You can change the visibility by binding a function. Set the different colours you want and then just swap the texts whenever you need.

I am new to Unreal Engine 4 and game making in general so there might be a smarter way to do this, apologies for misleading anyone.
Hopefully this is changed in the next versions of the engine; for some reason I failed to install 4.6.
