    RE: New colours in Ldraw? —William Howard
   Is this colour number "officially official" enough for me to go and fix this part?

   (...) We should probably put up a script on the website that reads the official config file, and displays a human-readable color chart. Steve (...) (20 years ago, 7-Oct-04, to lugnet.cad)
   
        Re: New colours in Ldraw? —Travis Cobbs
     (...) I don't want to come off the wrong way here, but is it really a good idea to be using a new color in a part so soon after it has been made official? You can pretty much guarantee it will look wrong in every current program if you do so. Also, (...) (20 years ago, 7-Oct-04, to lugnet.cad)
    
         Re: New colours in Ldraw? —Steve Bliss
     (...) Thanks for bringing this up, Travis. It's a very good point. The answer is: yes and no. The LDraw codes for new Stone Gray, Dark Stone Gray, and Reddish Brown were selected so that the original LDraw will treate them as Gray (color 7), Dark (...)

         Re: New colours in Ldraw? —Travis Cobbs
      (...) So, just so that I understand, are you saying that ldraw subtracts 64 from colors between 64 and 128, and uses that new value as the color? I wasn't aware of this behavior. (I understand it might not do exactly that; I just want to know if (...) (20 years ago, 7-Oct-04, to lugnet.cad)
     
          Re: New colours in Ldraw? —Steve Bliss
      (...) Yes, basically. LDraw color codes are bit-mapped. Bit 8 -> 0=normal, 1=dithered Bit 5 -> 0=opaque, 1=transparent (when bit 8 is 0) Bit 0-3 -> Color index (when bit 8 is 0) When LDraw goes to draw an opaque color, it does (color && 0xF) to mask (...)

         Re: New colours in Ldraw? —William Howard
     (...) ditto (...) So what colour would you use if not the official colour? Ok, so it may look wrong until the programs are updated to reflect what Lego is doing with it's colour palette, but is this really a valid reason not to use official LDraw (...)

         Re: New colours in Ldraw? —Steve Bliss
      (...) heh - I hadn't really caught the irony that the new codes will look alright in ol' LDraw, but will (currently) bomb in almost any newer program. :) (...)

         Re: New colours in Ldraw? —Bernd Broich
      (...) Good Idea. That's also my opinion. There should be a break with the backward compatibility. That would solve many Problems with the old DOS-Program. And it would be easier to generate new standards. CU Bernd (20 years ago, 9-Oct-04, to lugnet.cad)
    
         Re: New colours in Ldraw? —Travis Cobbs
     (...) I understand your point, but I think that it's a bad idea to release an official part that's guaranteed to look wrong in all current renderers. All that's going to do is confuse the novice users, and I think that's a really bad idea. I'm not (...) (20 years ago, 9-Oct-04, to lugnet.cad)
    
         RE: New colours in Ldraw? —William Howard
     (...) Ah, but according to the Colour Chart ((URL) "LDraw can render mixes of the basic 16 colors. This is commonly called 'dithering'. You can use dithered colors for any part reference, but part authors cannot use them to color polygons or lines. (...) (20 years ago, 10-Oct-04, to lugnet.cad)
    
         Re: New colours in Ldraw? —Chris Dee
     (...) That doesn't mean dithered colours cannot be used in a part, just that any area that requires such should be devolved into a subpart. There are plenty of examples of this technique in the official library - e.g. 973p39.dat Chris (20 years ago, 10-Oct-04, to lugnet.cad)
