Colour Inclusion Considerations

The main considerations on how LDraw colours are defined include:

• Use of LEGO RGB values
• Use of LEGO numbering where possible
• Use of Bricklink names
• All colours currently listed at Bricklink
• Lists the matched LEGO name
• Colours are grouped in categories
  
  

There is also an alternative file distributed with the LDraw.org Official Library that contains different edgeline colours: LDCfgalt.ldr. It is primarily intended for rendering and those who prefer their LDraw models to look more realistic in an editor. To use this alternative file, you will need to rename LDConfig.ldr to something like LDConfig_BlackEdges.ldr and rename LDConfig_Alt.ldr to LDConfig.ldr. Your chosen LDraw editor will thenload the alternative version at the next start-up. Please don't use LDConfig_Alt.ldr to make instructions.
