RAL Colours in Revit
Abdul Shaikh • 4 October 2019
RAL is a colour standard widely used in the Construction Industry
Revit does not come with in built RAL chart. By default, only colours Revit comes with is RGB & Pantone. In RGB system, each colour is defined by its associated red, green and blue attribute, whereas Pantone system uses a altogether different way of defining colours based on PMS number.
This all works fine for the graphics industry
where standard colours are defined in Pantone or RGB, but when it comes to the AEC industry, none of the colours - for example, for cladding materials etc. are defined by RGB or Pantone. This gives a slight issue for matching RGB colours to their nearest RAL colours as this has to be done in cases where a realistic render image of the design is to be produced.
Now thanks to Tobias Zetterberg from Autodesk Inventor forums who has painstakingly mapped each RAL colour to its nearest RGB value to provide us with a ready to use asset library. The file can be downloaded from our Tools section above (require email details)

A question was asked in a BIM forum: "We like to show the building elevation with 2 or 3 different color options for the client to choose from. Elevations do not change, just the paint is changing. I know I can copy the building over 3 times and give each one different colors, but these are massive buildings and I am hoping to avoid that. Also, I don't think we can use the "design Option" for the pain only. How would you offer multiple looks for the same building? Any suggestion would be appreciated." The simplest way to achieve this is by applying view filters to each of the duplicated elevations and then applying various colour / hatch options to duplicated elevations in the vg settings. For example - see above image showing four colour options for the same elevation. I have duplicated the south elevation four times, applied the same 3 view filters to each elevation picking out the family types that I needed in the options.
