Question Bar colour change?

Hi,

I'm very new to this, so please have patience.

I want to change the colour of some bars in a questionaire on my wordpress site. It was suggested I use H5P to do such a task but I can't for the life of me work out how. I'm sure it's a very easy tweak, but could anyone help explain to me how to do it?

I've included some screenshots to help explain what I mean.

https://ibb.co/RP1ShwV - As you all know, changing the colour in the inspect option doesn't save it. 

https://ibb.co/26NPyJK - these are the current colours

https://ibb.co/LS22zJ2 - I'd like them to be these colours!

Any and all help is appreciated. Please remember I am new to this but I will do my best to keep up and learn. 

Thanks in advance,

Matt
