Describe the bug
Colors of activities Time Clock assigns randomly does not differ enough, which makes the chart hard to read.
Expected behavior
Time Clock chooses from a large pre-defined set of colors and try to avoid using the same for different activities or generates them in a way, that it's easy to distinct them.
Observed behavior
I constantly see either purple or green.
To reproduce
Add multiple activities.
