  This is right as far as I can tell: gideros only handle RGB, either with separated components or with 0xrrggbb representation depending on the function.

  to whoever might be interested in colors ( @hgy29 maybe you might, since you're "the king of Shapes" to me )
  
  I just found something that seems wonderful:
  
  http://sputnik.freewisdom.org/lib/colors/
  
  
  just played with that a little, i'd say that there is only one requirement to let it work with gideros:

  --change module(..., package.seeall)   --to   module("colorLib", package.seeall) --I wrote "colorLib", I suppose that a string is good as another. I am still trying to understand what should the ... operator do in that position.

  it doesn't export hex colors but should be just a temporary issue, until we find the right transformation function... rgb2hex()

  and back:
  
  
  function hexToRgb(hex)
  local blue=hex%256
  local green=(hex-blue)/256 %256
  local red=(hex-blue-256*green)/256^2
  return red,green,blue
  end
