You should be tapping the 12-bit output of the array (the read side of the memory). It's not clear from your waveform screenshot whether you are doing that or not. Can you show how you have the node list set up on the Signal Tap configuration tab?
If your memory is not implemented using memory blocks (using logic blocks instead), then in theory you could tap each memory location, though it would require diving into the Node Finder to find the appropriate signals. If it's implemented using memory blocks, you would not be able to tap into the memory blocks themselves since there are no wire connections coming out of the memory blocks for each individual bit.
A better method would be to tap the write side of the memory and the address lines to see what data is going into which location and then look at the read side along with the address lines to see what data comes out.
Hi. Here's a link to what I'm seeing in the Node Finder:

So should I be including colorRGB.data_a[0] thru colorRGB.data_a[11] in my case?

Yes, select colorRGB.data_a to select the whole bus.
