My favorite color is yellow. But I'm not keen on using yellow for this. Can you show what it currently is using?

I agree the blue is hard to read. But I don't think the bright yellow is much better. I think a light blue (like the hover row color) would work well. It does not need to be so in-your-face to notice it.
I chose yellow because it has the highest luminance. http://www.workwithcolor.com/color-luminance-2233.htm For our case, out of all colors with the same saturation and lightness, yellow would produce the most readable text.
Also, the red color we use for attributes, hsl(1, 79%, 42%), is fairly light. It doesn't give us too much flexibility with the background color — it's very easy to produce low contrast unreadable text.

I had to use QuickTime to do the screen recording because LICEcap altered the colors too much.
I also think that attribute changes on the selected node should still show flashes. It definitely needs a different color (blue on blue is just bad), but it should show that there is a change regardless of if the node is selected.
