Now that there is some support for node POWER colours and custom colours for positive/negative values in the tooltip, the search of the nodes is still RED highlight on dark (default tree bg) background. Which I personally really can not see at instant, so to find a node in the tree using search I have to rescan whole tree with my eyes to try to catch that red circle. I am sure people with same colourblindness problem would confirm (not the green-red guys, more like dark red / dark green guys) the same problem :)

Describe the solution you'd like

Add a similar setting for highlighting searched nodes on the tree as it is now for "Node Power colours" (so a predefined green/blue colour) or a Hex colour setting.
Hex colour would be best, because that would allow people with different vision problems to choose the right colour for themselves. As for me personally - best would be bright yellow, or something that otherwise stands out of dark background of tree/nodes A LOT. But that may not be the case for other people.

One easy solution would be to reuse the negative hex colour option.
