The one thing we do hope they add soon is a search bar in the Color Books window. They do have a Color field but we have found that you have to be pretty specific for it to work. The nice thing about Color Books is that there are some available out there to download and use since they have been around for so long. For example, we added PPG Voice of Colour library to mine by adding the .acb file to this location: C:\ProgramData\Autodesk\RVT 2024\Colorbooks
