I just tried something straightforward (for me):

dummy = Import["http://pastebin.com/raw.php?i=g8D7NprC", "List"] & /@ col;
colors = dummy[[1]];
ToExpression@colors;
Graphics[{colors, Rectangle[{0, 0}]}]

Is it not possible to import color data from a file?

  • $\begingroup$ it works fine if you remove & /@ col at the end of the first line. $\endgroup$ – kglr Jun 3 '14 at 20:10
  • $\begingroup$ Ok I don't know much but now there is nothing happening. No output at all. Which is very weird when it works fine with you. It states "RGBColor[0, 0, 1] is not a Graphics primitive or directive" $\endgroup$ – MaxJ Jun 3 '14 at 20:17

    $\begingroup$ I think it is because your colors is a string; to change it to a color directive use ToExpression@colors... $\endgroup$ – kglr Jun 3 '14 at 20:25

    $\begingroup$ Or just color = << "http://pastebin.com/raw.php?i=GXbeGrcD". $\endgroup$ – user484 Jun 3 '14 at 20:25

    $\begingroup$ @user3683367 - you oversimplified your question. what does your file to be imported REALLY look like? does it contain DIFFERENT colors, a list of colors ? But even in this case: How, exactly, do you want to color ONE rectangle with these different colors? $\endgroup$ – eldo Jun 3 '14 at 20:40

I think you need something like the following:

 dummy = Import["http://pastebin.com/raw.php?i=g8D7NprC", "List"];
 colors = ToExpression /@ dummy;
 Graphics[Thread[{colors, Rectangle/@ RandomInteger[10, {5, 2}]}]]

  • $\begingroup$ Yes this is exactly what I wanted. Would you recommend using "Thread" or "Sequence" like in the following question: mathematica.stackexchange.com/questions/48818/… $\endgroup$ – MaxJ Jun 3 '14 at 21:38

    $\begingroup$ @user3683367, you probably will be using this in an animation similar to the linked question; so i would recommend using the same setup... that is, {colors[[t]],Rectangle @@ (rectCoords[[t]])} with t the index you use in Animate or Table... $\endgroup$ – kglr Jun 3 '14 at 21:52
