Multiple colour versions of the same images should ideally be within the one upload archive, and no, they won't displace the individual uploads.

Another 'problem' arises when the icons [in this case] are cut out of some other image and are not actually original works of the uploader but appear to originate elsewhere....in which case they 'shouldn't' be submitted/approved.

The best 'results' are had by NOT uploading every single thing you create...but by being selective to a self-imposed standard.  It improves the public's perception of your work/standards/quality.

[that's why I have so few uploaded, myself]....
