Dismal icons and other things I don't like?

[Richmond]

This is where I am asking for some legal help.

I intend to make colour replacement png images for the monochrome png 
images I don't like
in Livecode 6.x.x and offer them in a stack with a button containing a 
replacement script, as well as a button
that will restore the monochrome png images.

I would like my coloured png images to be Open Source in exactly the 
same way as LC 6 is.

So, presumably, I have to attach some sort of legal rigmarole to the 
stack, otherwise the "We patent swings" brigade
can grab them and say that they are theirs and one has to stump up 
moolah for them.

Grateful for advice.

Richmond.
