http://www.webexhibits.org/causesofcolor/2.html is good for more practical examples of colour-blindness in action.

Blue-yellow deficiency is trippy as ♥♥♥♥, my god. I mean seriously.

And speaking of visual impairment, time to violate your eyes with my super lousy (read: entirely absent) digital painting skills.



IT BURNS

Wow Shook. That really is... Different.
Please. Stick to your delicious pixely goodness.

Worry not, i'm only rarely stricken by the need to make something that isn't pixel art. :U
That said though, i wouldn't mind a tip or two, if at all possible. It probably all boils down to "PRACTICE MORE, BUTTNUGGET", with which i agree! (except that i probably shouldn't show it publically before it gets less like acid + eyeballs, because technically this thread is labelled ART dump)

PRACTICE MORE, BUTTNUGGET

But actually, your colors are really muddy, like you used a semi opaque brush to paint that. You should lay down the solid base colors before you think about touching the transparency settings.

Dude that is trippy as hell. I like it!

@madmax: Alright, i'll try that next time. How you could see that i used a semi-transparent brush through all that smudging is beyond me, but nicely spotted. :v

Then I have more for you

That one looks really, really good. I liked the colors.

Are you doing that with long exposure time or some sort of new-age computer witchery?

These are 30 second long exposure photos.

I think you should do one where it looks like you're shooting a goddamn kamehameha or something.

Jeez dude you are good at this kind of stuff. Round of applause for Emo!

Only thirty seconds?
That seems like a lot of movement for only thirty seconds.
Are you diagnosed with schizophrenia, Emo?

I didn't realize schizophrenia caused one to move rapidly and erratically.
