As mentioned here, the syntax to filter Color (no quotes) is different of BackGroundColor3 (double quotes).
Besides that, there should be an example with BackGroundColor3 as mentioned in that post.
Hi there, thanks for the report! I’ve corrected the citation in that property types that are complete “units” like Vector3 or Color3 need quotes around them.
BackgroundColor3 should work the exact same as Color3 (both need surrounding quotes) so I didn’t include a specific example for BackgroundColor3.
