is tamarind supposed to be dark black?

I bought a jar of tamarind from my local indian store. Initially, i had no idea tamarind was supposed to be this thick dark black color. I thought it was red.

I’m trying to make pad thai, and it’s bugging me that i can’t find tamarind. Now that i found it, i wasn’t expecting it to be dark black.

Did i buy the wrong thing? Is this the wrong kind of tamarind?

Am I supposed to use the pre-made tamarind sauce from Knorr?
