You are definitely not alone with your problems using black yarn for crochet. I cannot imagine how exhausting it was to crochet the beautiful lace part of your top (by the way I love it!!!). Sadly, I do not have any tip how to make it easier. I think its in the nature of crochet; other than in knitting one must look at the stitches in crochet to find the right loop to insert the hook. Knitting is a bit easier in this regard as you have the loops always on a needle, so if you are very skilled (which I am not 😱) you can knit completely without looking.
Without a tip, still, I'm thankful for your comment. It just means that I'm not alone and we share the same struggles. Anyway, thank you so much for appreciating my work and reading my post. 🥰
