Hi Erika,
Leadwerks changed the API quite a while ago for the color settings. Colors no longer have to be divided by 255 in order for them to be processed correctly by Leadwerks.
so this:
self.backgroundColorFractioned = Vec4(c.x/255, c.y/255, c.z/255, c.w/255)
becomes:
self.backgroundColorFractioned = Vec4(c.x, c.y, c.z, c.w)
