Based on the video context from the first video, it seems that the color "Mellow Yellow" is a great choice for bass fishing on Pickwick Lake. The angler in the video mentions that it is a color that works year-round and is their new favorite. However, it's always a good idea to have a variety of colors in your tackle box to experiment with and see what the fish are responding to on any given day. Different colors may work better depending on the time of year, water clarity, and forage availability.
In the second video, the angler mentions that in clear water conditions, black and chartreuse and Purple Sage are go-to colors. So, if the water on Pickwick Lake is clear, these colors could also be effective.
Unfortunately, the third and fourth videos do not provide specific information about crankbait colors for Pickwick Lake. Therefore, it's best to rely on the information from the first two videos.
Remember, fishing can be unpredictable, and what works one day may not work the next. It's always a good idea to experiment with different colors and techniques to see what the bass are biting on.
