How to read that information from the file system ?
Here is a NSWorspace category that will give the label colours.
Note that if you plan to use these colours to draw text instead of rounded boxes, you may want to replace the [NSColor clearColor] by [NSColor blackColor]
@implementation NSWorkspace(FinderColors)

static BOOL sFinderColorsInited=NO ;
static NSColor* sFinderColors[8] = { nil, nil, nil, nil, nil, nil, nil, nil } ;

static void initFinderColors(void)
{
sFinderColors[0] = [NSColor clearColor] ;
sFinderColors[1] = [NSColor colorWithCalibratedRed:(168.0/255.0) green:(168.0/255.0) blue:(168.0/255.0) alpha:1.0] ; // gray
sFinderColors[2] = [NSColor colorWithCalibratedRed:(174.0/255.0) green:(216.0/255.0) blue:( 65.0/255.0) alpha:1.0] ; // green
sFinderColors[3] = [NSColor colorWithCalibratedRed:(194.0/255.0) green:(138.0/255.0) blue:(217.0/255.0) alpha:1.0] ; // purple

sFinderColors[5] = [NSColor colorWithCalibratedRed:(235.0/255.0) green:(219.0/255.0) blue:( 65.0/255.0) alpha:1.0] ; // yellow
sFinderColors[6] = [NSColor colorWithCalibratedRed:(252.0/255.0) green:( 99.0/255.0) blue:( 89.0/255.0) alpha:1.0] ; // red
