Custom Hit box for frames?


I’m just messing around with something & I would like to know if there is a way to make a button hit box conform to a mesh/clip around the mesh? I have a logo that has been cut into sections (based on colour). I want each colour of the logo to have its own mesh that the user can hover/click over & it will take them to the a new page. However they overlap with the standard rectangle/square frame hence causing my issues.
