Fro reference, here's another screen shot of the lores colors:

I'm running KEGS 0.91 on Mac OS X 10.4 with an Apple Studio Display. On 
my screen, the colors look comparable to your AppleColor-KEGS.png. 

Here's the tortured one-liner that printed the picture:

1  GR : HOME : PRINT :
   FOR X = 4 TO 35:
     COLOR = C: H = C > 9:
     POKE 1616 + 128 * U + X, 176 + K * (C - 11 *H) + H:
     VLIN 0, 39 AT X:
     C = C + K: K = K = 0: U = U = K:
   NEXT
