findWaterColor has been broken since the Easter update, i forgot because i fixed mine right away
anyways, i forgot the only posted fix is in the members sections so here's mine so you can run my script 
SCAR Code:
function FindWaterColor: Integer;
var
i,mx,my:integer;
begin
for i:=0 to 50 do
begin
if findColoredAreaTolerance(mx,my,12162685,mmx1,mmy1,mmx2,mmy2,50,i) then
begin
result:=getColor(mx,my);
writeln('watercolor = '+inttostr(result));
exit;
end;
end;
writeln('watercolor not found!');
end;
it has worked 100% for me, but idk. Just put that in your includes/srl/srl/core/autocolor.scar, and also next time you update your SRL through subversion you will have to do a cleanup or just delete your whole srl folder, otherwise you will get errors in your new version.
