Whew, that's great news!
Hahahahaha, that's the default colors from the Kibana widgets... I usually
refrain from bringing it up, but I'm partially colorblind (even though I used
to do a fair amount of Photoshop graphic design work on the side, but it's a
bit more effort for me). Anyhow, Kibana had no easy way to pick color names or
supply RGB values, so I punted on it for now because I figured that's an easy
change. If you would be willing to take a screenshot or the xy coordinate of
colors in the color picker that you'd prefer, I'd be more than happy to change
it.
