Of course I am dark colours. I appear gloomy and bitter, I seem depressed and my character is drawn with a permanent frown on his face (albeit due to Strop being, well, Strop).
It seems fitting.
Still wondering why no one has pitched me with some greys, but I guess I am a bit more colourful, huh.
I do like the reasons, though. It amusing to read.
As for people I haven't coloured up, just real quick.
Murasaki:

Girlygirl colour, but a more modest shade, more faded and more fitting for some of what you write.
Ghost:

A good reliable colour, not quite green, not quite blue, but still the colour of water. Fresh and still faded and calm.
Jeol:

Not so much a colour as going for an outline, without being the boring black.
Frank:

Colour of dirt and wood. Sturdy, would punch you out in a second. Also a good colour for dwarfs.
Salvidian:

New blood, fresh, energetic, around. Kinda in you face, but without being so in an annoying way like yellow or neon-colours.
As for anything else, well...
Yes, Gantic, you are quite blue, but only in colour, never in mood. I guess most of us find you to be a force of nature, like the ocean or the sky, which tend to be symbolised by the same colours. You are the modtornado, after all. And, well, who were we, if we couldn't give you a colour with alternate meanings, oh pun-bun of the sky.
Yup, Frank, I often find Gantic horrifying. To tie it with the above, it is mainly the horror of silent respect, like you have to the big waves and the strong winds, because you know they could kill you any minute, or in the case of Gantic, ridicule you in several ways, most likely in a wordplay, and everyone would know.
As for being myself on the forums, well... I don't particularly like myself, he's an annoying sod and swears way too much while writing in caps and making stupid jokes about Strop, while Strop makes stupid jokes back. I think it's for the better I am just this.
So, there. A legit bump, let the discussion continue.
