So on AVForums, we've had to create a whole bunch of colours in the palette and assign them to the node classes in order for different areas of the forums to have different colours.
Here is how it looks on the Which TV... forum, child of the Home AV category which is designated blue
and the Movies forum, child of the Movies, TV & Music category which is designated red.
For each forum colour, we have a medium colour, a lighter and a darker version, and these provide us everything with we need for each node. But there are lots of new colours in the palette.
And we have to put a load of css in to assign the colours to the various elements - this is just a small snippet of the css for one colour.
For Xenforo 2, could we have an easy way to assign colours to specific nodes, which are inherited by their child forums unless the child forum has its own colours assigned?
