KIRUPA ICON GALLERY / PIXEL 16 X 16 ICONS - CREDITS

1,948 pixel icons by kirupa.com, hand-drawn on a native 16 x 16 grid.
Native 16x16 pixel art in the 8-bit icon tradition. Each subject is reduced to its essence and redrawn in the view pixel art does best, often a flat side profile. One hard black outline runs round the silhouette; inside it, parts are separated by tone, and black is kept for holes and openings, deep crevices, face features, overlaps of similar colors and line-art symbols. Solid forms take one light from the upper left; symbols, flags, print, glows, water and screens stay flat. No anti-aliasing. Every subject is hand-drawn on the 16px grid, not resized from another size.
