as long as you create the parts in hype you can colorize the properties of those parts in timelines.
an image or imported svg can just be colorized and sized over all ...
There is an old thread showing a way this can be done
Changing image hue and/or saturation.
No JS just relative Timelines
Here is an update of the last example ( add hue colours for the rims ( using single image )
testSeats.hype.zip (1.7 MB)
But read the thread..
