Julia logo graphics


#1

FYI, you can get some information and source files for Julia logos and other artwork here. It’s not a package, just a repo.


#2

If anyone needs an animated logo - it’s here:

import GR

macro codes(n)
  return :( [GR.PATH_MOVETO; repmat([GR.PATH_CURVE4], 3 * $n)] )
end

Cool, though the colours (especially the green) are slightly off.


#4

My best guess as to the RGB color values in the original was:

darker_blue = (0.251, 0.388, 0.847)
lighter_blue = (0.4, 0.51, 0.878)
darker_purple = (0.584, 0.345, 0.698)
lighter_purple  = (0.667, 0.475, 0.757)
darker_green  = (0.22, 0.596, 0.149)
lighter_green  = (0.376, 0.678, 0.318)
darker_red  = (0.796, 0.235, 0.2)
lighter_red  = (0.835, 0.388, 0.361)

I’ve sometimes wondered, in an idle moment of post hoc rationalization, whether the four dots represent the four creators of Julia (The Four Horsemen…). Only Stefan knows for sure (although it may have been unconscious…:).

I improved the script - thanks for providing the RGB values …
