How do I say I'm wearing black pants?

"Llevo pantalones negro." or do I have to add an "s" to negro?

Thank you

Absolutely! Here is the basic rule for adjectives in Spanish. Find the NOUN and then all adjectives will have the same number (either singular or plural) and gender (either masculine or feminine) as that noun.

los pantalones = is plural and masculine
negros = now it matches because it is also plural and masculine.
