Background Color on Actions

[BaileyHedstrom]

I would like to be able to change the background color of actions. We can do this with blocks and I often place blocks around data items to label and associate them with a specific action for it's inputs/outputs. Changing the font color is somewhat helpful, but some of the colors are difficult to read. For readability, it would be nice to have the action color match the block color I use to associate all of it's data items.
