Recolor? Should i read rules, if i gonna upload an icon? Why you ignore this question?
Honestly, there's no reason to be too harsh on newcomers who upload recoloured original Blizzard Entertainment icons.
I have always understood why newcomers haven't read the full submission rules set of the respective sections, because they are (still!) hidden in their forums...
For example, the rule concerning recolours, which can be read in the Submission Form, is incomplete and phrased inprecisely.
What exactly are those "certain purposes" ? What exactly does "author created" mean (it's pretty simple when you know it, but people with lacking English skills will have a hard time grasping its meaning the first time they read it) ?
The updated Submission Rules, which are present in the forums, are up-to-date and phrased as efficiently as possible. Them being hidden like this is a malady we have to live with for the time being.
Now, this
can be acceptable as a recolour of an original Blizzard Entertainment icon, as can be read
here.
However, there's the issue of "usefulness".
I am not sure if moderators will even put this in Blizzard user profile since basically everyone with any photoshop skill can do it.
This would apply to any other recolour, but does not concern recolours of Blizzard Entertainment icons.
Yes, anybody with a very limited understanding of how to work with GIMP and the like can do this, but the category "usefulness" exists for a reason in these cases.
It's up to enjoy to decide whether this submission satisfies the necessary requirements.
