I think all those resistors you are referring to are 1% resistors and use a different color code. They look like red-yellow-black-black-brown which is a 240 ohm 1% resistor. I agree the colors don't look completely accurate in the picture, but that may just be a photographic anomaly. Assuming all these resistors came from a coop, it's unlikely they are incorrect or any 24 ohm resistors even came in the kit.
