Describe the bug
The team overview and scoreboard dashboards briefly display as greyscale before reverting to the red/green colorscheme every refresh, which causes the dashboards to appear to "flash".

To Reproduce
Steps to reproduce the behavior:

1. Log in to Kibana
2. Open an Overview - {{ GROUP NAME }} dashboard or the Scoreboard dashboard
3. Observe the flashing between greyscale and color

Expected behavior
The visualizations should stay a solid red/green color, and shouldn't flash every time the dashboard data refreshes.
