[fpc-pascal] Syntax to select constant or variable with function call

Yes, it should be, Also noticed a typo in my groupings, it wouldn't  
affect anything but I like to make it clear.

So now I have this for the function:

function Find_Color(Constref ColorArray :TVGA256Array; R ,G ,B : Word) : Byte;
Var
   Dist,Closest:Double;
   I,BestChoice:Byte;
Begin
    Closest:=200000;
    For I:= 0 to 255 do
       Begin
          Dist := ((R-ColorArray[i].R)*(R-ColorArray[i].R))
                + ((G-ColorArray[i].G)*(G-ColorArray[i].G))
                + ((B-ColorArray[i].B)*(B-ColorArray[i].B));
          If Dist < Closest Then
             Begin
                Closest:=Dist;
                BestChoice:=I;
             End;
       End;
    Find_Color:=BestChoice;
end;

I have 2 arrays that are not [0..255],  one is [1..14] the other is  
[0..15] is there a way I could expand this scheme to use those arrays  
as well?   The For loop would need to adjust to the size of the arrays  
somehow.
