Copyright and trademark licenses, logos and color chart [Sonic Pi]

hi, this topic is a bit special, and i didnt see anythings about it on the forum.
i got a bunch of question regarding the use of the Sonic pi logo and others elements.

Can we use the logo Sonic Pi ? what conditions ? modifications are allowed ?
what is the state of such topic ?

also, i would be interested to understand correctly the next objective of Sam, regarding the use of visuals and audio to promote the software in schools and on-line…thx
