i need some help to plot a three colored Trefoil knot. I found on Wolfram the code

Graphics[Transpose[{{Red,Blue,Green,Red},KnotData["Trefoil","KnotDiagramData"]}]]

for the three colored Trefoil but i want the line segments thicker.

Can someone help me please and maybe give a another example for a 3-color Knot?

You can pack all of that styling into a Directive.

For a general function that'll work no matter what styling choices, you can try this:

With[{
  d = KnotData["FigureEight", "KnotDiagramData"],
  individualStyles = {Red, Blue, Green, Pink},
  commonStyles = Thickness[.05]
  },
 Graphics[
  Transpose[{
    Directive @@ Flatten[{commonStyles, #}] & /@

     Take[Flatten@ConstantArray[individualStyles, Length@d], Length@d],
    d
    }]]
 ]

asd

Just tweak the stuff in the With variable declarations
