I dont think you have create them by accident, i did not know how to and it is not the default name “Col”.

Anyway you can use a script for it:

JacRossiter/Jaks_Blender_Scripts/blob/master/Vertex Color/Remove_vcols.py

import bpy

for ob in bpy.context.selected_objects:     # Loops through sselected objects
    bpy.context.scene.objects.active = ob   # Sets current object as active
    while len(ob.data.vertex_colors) > 0:   # Delete vcols
        bpy.ops.mesh.vertex_color_remove()

My operation steps: import FBX externally, separate P first and obtain 100 submesh. It is found that vertex colors cannot be deleted in batch.

If it is created in blender, it can be deleted in batch, but I selected several models and deleted all vertex colors in batch. It’s strange.
