Answer
What type of crab is it? Some crabs will have that appearance when they molt which is a process of loosing the old outer body covering and will take a bit of time for it to return to what is the "normal" external coloring. I have had red claw crabs that would fit your description when they molted. You most likely may also find the molted shell in the tank which will almost appear to look another crab but you will notice a difference in weight as they shell alone is much lighter.
If molting is the case which is most likely how it sounds your crab is still alive, don't throw it away. Hopefully this gave you some insight to your crab situation. Best of luck.
