Color DL columns for activity

[pjotrp]

We would like to color the DL columns for activity. Here we should not just use the DL number, but a delta, as I did for calculation the arrows. Wat is interesting is not the pure DL rate, but the difference over a period. What needs to be done is to sort both total DL and 90-d DL lists, and create a color gradient based on the difference. We can use the same color for both boxes for each biogem. How is that for an idea?
