The process was bloody tedious but the site's now even colourfuller - this is Vega 2.
Grey's now an endangered species about these parts. ...Well, proper grey - all of the “black” text is actually grey, bar the main title. But you see my point - more colourifficness. Yay.
The aforementioned tedium came from having to calculate several background colours for each hue - 60 colours in total. It was just a matter of typing one number into Inkscape and copying out the colour code generated by it, but it was somewhat boring to do sixty times.
Just too much dedication - that's my problem.
