Storyline: Customizable Accordion Freebie

I'm using this template but my pages are different colours. Is there a way for the colours to transition as the bar moves across? For example, if the Record Keeping page was green, could the grey lined page slowly get smaller as a green page gets wider as the Record Keeping bar moves across? Hope that makes sense. Thanks.

Can you please help me find the steps to create this accordion?

I can't wait to use this! Love it!!
