Chart is the successor to Familytree; both were developed on Wikipedia and you can import from there. However, there really isn't much in there in terms of lines. Just straights and dotteds. If you read through the Familytree or Chart documentation, you'll see how the lines work. You can't change color on a case by case basis, you'd have to add new parameters for every line combination, for every alternate color, at the very least. What you like is impractical within the existing framework. You'd have to try your hand at customizing your tree templates yourself, as this is not a quick and easy fix anyone will just do for you. Consider adjusting your expectations and work with the template as is. The standard is solid line for children, dotted for couples and exes (like children, usually ordered l-r to denote chronology). You can also just add (adopted) to the entry of the adopted child.

The tree templates are complex and hard to wield, but in all the years of wikitext, noone has come up with a better flowchart/family tree template in mediawiki. Sometimes, you just got to row with the oars you got.
