Since the Google Chrome update of tab groups, I always use them. I use the whole default available palette, which draws like this:
{% katex %} \colorbox{#e2e3e5}{\color{#e2e3e5}{X}} \colorbox{#fff}{\color{#000000}{tools}} \colorbox{#3871e0}{\color{#3871e0}{X}} \colorbox{#fff}{\color{#000000}{infra}} \colorbox{#c84031}{\color{#c84031}{X}} \colorbox{#fff}{\color{#000000}{watch}} \colorbox{#eeae3c}{\color{#eeae3c}{X}} \colorbox{#fff}{\color{#000000}{branch}} \colorbox{#3c7e40}{\color{#3c7e40}{X}} \colorbox{#fff}{\color{#000000}{suite}}
