Visual clarity on passive tree

I'm taking the privilege to write about the lack of visual clarity on the passive tree. Assigned nodes, weapon set 1 nodes and nodes "you can path to next" all look the same. I'm luckily not colorblind so I can't even imagine how hard it must be for those who are colorblind.

I'm also not a programmer but surely changing a RGB code takes less than 5 seconds. Please fix it ASAP. This should not wait until 0.5, nevermind the fact we're a year in already and still have this issue.
