Um, what? This is an area of pixel art, and art in general, that i have to step up and DISAGREE!
Why?
On every computer that's ever made, does arne own color 199, 134, 162?
On every pixeling of a flower, does so and so own colors 187, 356, 234 and 155, 256, 121?
No.
So an artist sees a particular game and uses it's palette. He makes some work with same palette. A crit says, nice, but it uses such in such palette so its not his own work. Or it uses this person's palette so it's not his own work. Or it uses this games palette so it's not his own work.
What?
Who owns a part of the color wheel? Who owns any peice of light? Who owns a randomly pulled up set of colors that just happen to look alike so people say, you copied off of so and so so it's not YOUR work.
While it may not be okay to use someone elses work. I don't see a problem with using a specific set of colors.
It is ubsurd, ridiculous, hindering, and down right ego tripping.
My answer is NO. You shouldn't have to give credit. If you make something awesome with a particular set of colors, that's cool with me.
So, in effect, I don't own red, YOU don't own Blue, and ARNE DOESN"T OWN GREEN!!!
No else one should give a care what set of colors you use either.
And if they do, they should get a reality check.
(i highly doubt I'll get any backing here, siince everyone worships particular artists to the tee, and any hint of territory infringement is pounced upon and silenced. or there made fun of and picked on in some way to have the same effect. which, in my opinion, is downright sad)
