Idk about the color struck thing. Personally, I'd never have a kid with a White woman but skin color in regards to genetics is weird..
My great great maternal grandma was White. Her daughter and my great grandma was mulatto and she had kids with a partially Black, partially Native American man. Majority of their kids came out light skin or light brown, as you'd expect. My grandma had 9 children by different men, most of them being regular brown Black men, only 1 of my aunts/uncles is brown and the rest are yellow. Kind of goes against the "they'll be darker" theory. Now, my mom is yellow but my dad is dark brown and I'm light brown but my sister is lighter than my mother so it's not really an exact science to skin color if you already have recent and prominent admixture in your blood. Even the "White" people with a recent Black relative have that weird facial structure and slightly tan skin tone that you can tell them motherfukkers aren't pure aryan i.e. Jason Kidd
At the end of the day, you love who you love. Not seeing how solely fukking with a dark skinned woman because you want dark babies is different than fukking a non-Black woman for good hair and light eyes.
