How to change the color and appearance BonitaSoft 5.0

Hello everyone wanted to help me change the appearance of my process nice 5.0 and the portal as this very technical

Thank you so much

I’ll be honest most people are moving away from 5 so unlikely to be able to help.

I would start the move to 6 or 7 before changing anything more in 5 as it will soon possibly be out of support from Bonitasoft (I think it is two version s back only that are supported).

regards
