Apple is rumored to be working on mini-LED versions of the iPad Pro, and it's possible that a new Apple Pencil could be unveiled alongside the upgraded tablets.
Apple also already refreshed the 11 and 12.9-inch iPad Pro models in March of 2020, so it seems unlikely that we're going to see a new Apple Pencil at any point in 2020.
Both the original Apple Pencil and the Apple Pencil 2 designed for 2018, 2019, and 2020 iPad Pro models are available only in white, even though the iPad itself comes in multiple colors.
Apple could perhaps in the future offer the Apple Pencil in a few colors matching the available finishes of the iPad Pro models
