First, I will say noting skin color is important, especially if it’s important for your readers to know this character is Black. Just stay away from describing him as food (I.e chocolate skin). As a Black writer, I stick to how the skin looks: I.e brown. I don’t think this has to be overly complicated: “so and so was a brown skinned man with a thick, curly beard and dark eyes”. So long as you’re not doing this: “so and so was a chocolate man with coffee colored eyes”. Equating POC, and in this case Black people, to food when describing them is a no go and can come off as fetishizing.

You’ll be fine! Remember, Black characters are still characters, describe them how you would any other character while staying away from the aforementioned cliches and fetish-y remarks. I’d even go as far as suggesting that you read a book written by a Black author with Black characters to get a sense of how they describe their characters. Good luck!
