Need help with getting this blending color effect to work

I really enjoyed this UI effect, and wanted to try re-creating it, but I’m having a bit of trouble.


From what I can see, there are 3 semi-transparent UI’s, being Red, Green and Blue, and since they are transparent, they can mix together to create other colors, mostly White in the middle, and Yellow, Cyan, and Purple around randomly from mixing.

However, when trying something similar I get this ugly blob, which barely mixes, and I’m not exactly sure why/how it doesn’t work.

I can easily handle the scripting part of movement and sizing, I’m just not sure how to get the color mixing down.

Any help would be appreciated!

It might be an animation the more I look at it, every movement is repeated, it seems to only last a second. So it might not actually be as I thought.
