I stressed far too much about only packing neutrals.
Everything I saw, read, and heard leading up to my safari trip emphasized the need to pack neutral colors.
Olives, tans, browns, and khakis were good. Blues and blacks were a no-go since those colors attract tsetse flies, which carry a sleeping sickness disease.
Meanwhile, bright colors can alarm and scare off animals.
As someone whose wardrobe consists of 80% black clothing, discovering this was a major stressor, and I ended up on a shopping spree before my trip.
But when I spoke to van Niekerk right before my trip, she reassured me that safari attire is much more casual and flexible than I had read online.
Her advice is to pack what you already own. Don't stress too much if you don't have a complete khaki-colored wardrobe. Instead, prioritize neutrals where you can. She added that you don't need to avoid colors completely.
Besides a walking safari, there was never a time when I felt like the color of my clothing would have impacted my trip or animal viewing. By the end, I regretted buying clothes I might not wear again.
