You can make an array of color codes and use it with OpenGL. Something like:
Code: Pascal  [Select][+][-]
  1. type
  2.   RGBByte = packed record
  3.     r,g,b: byte
  4.   end;
  5. ...
  6. var colors: array[0..255] of RGBByte;
  7. ...
  8. glColor3bv(@colors[16]); // Would use index color 16 for all next drawings

If you're using OpenGL you should use proper OpenGL data types for the sake of portability (i.e. GLbyte or GLubyte instead of BYTE).  Also glColor3bv receives an array of bytes, so:
Code: Pascal  [Select][+][-]
  1. TYPE
  2.   TRGB_Interval = (rgbR, rgbG, rgnB);
  3.   RGBByte = ARRAY [TRGB_Interval] OF GLubyte;
  4. ...
  5. VAR
  6.   Colors: ARRAY [0..255] OF RGBByte;
  7. ...
  8. glColor3bv (@Colors[16]); { Would use index color 16 for all next drawings. }
Just as suggestion.

Hey, I'm back! The colors work like a charm. I wrote a script that transforms the legacy artwork of mine to svg or whatever format I would need. I attach a small teaser image :D

Is that a gold mine?

Yep, exactly. There is some inconsistency, as you see on the picture. In the original there were no brown color, that was also a greyish color. Still have to figure out why my R script turn them to brown :P
