Spanish speaker plss help me i don't speak Spanish

Moreno is spanish for brown and I am pretty sure that the opposire is dark blue

Bajo means low, therefore, the opposite is alta/alto

Malo means bad and the opposite of that is bueno

Serio means I laughed and there could be a few different ways to answer this but I am going to use, I cried which is llore

And menor means less so mas is the answer

Explanation:

Hope this helps :)
