Erase all chart links and add more colors for chart link options

Sometimes I don’t remember which color each link is connected to so when I use a color to for a link to a product I found the color was already taken. So there should be an option erase all links to each chart so when I pick a color the chart dost change to another product I did’’t want the color for.

Lastly there should be more color options to link charts, DOM’s and orders so there will be less issues of then getting mixed up.
