Network colors from a scale

[davkal]

• network-name independent
• all colors are unique and separated enough
• only 10 colors are available
• contains red and green

Is this meant to fix #1592?

network-name independent

Does that mean the same network may be coloured differently, depending on context?

[davkal]

It's a hack that fixes #1592 for network counts <= 10.

The colouring depends on the order of which we see the networks for the first time. That means it's stable while you keep the browser window open. It may be different if you reload or visit scope at a later point.

To fix this properly, I would work on a proper solution in #1567

I think its a good, safe solution for now, will work well for demos etc.

I'll give it a test.

network counts <= 10

what happens when you have more? Colours get re-used? Or does it explode?

Repeats. category20 gives us 20 tho...

cat20 is not distinct enough. It's 10 hues, with 2 different shades each:

We could brew our own color scale...

stick to cat10. merge it. move on to #783.
